T2i Lens error message, now not taking pics
About a week ago my t2i gave me an error message saying it could not read the lens. Switched out to a different lens and it worked fine for about another week. Now it's struggling to take pictures. Any thoughts on what to do next? Would a good cleaning take care of the issue?
A camera will allow the shutter to activate even without any lens attached at all.
Remove the lens, press the shutter button. Does this work? If so, the the problem is likely the lens. It's possible theres a communication error on the camera side, but it's FAR more likely on the lens side because that's where all the moving parts are located.
Specifically which lens(es) are you using?
Check the pins on the camera (and these AE spring-loaded.). Make sure they spring in and out easily and that none are jammed.
If the pins or contacts are obviously dirty then you can clean with a soft cloth (don't use anything abbrasive.... The gold plating is thin and easy to rub off if cleaned too aggressively). Usually it is not dirty contacts. These problems are mostly inside the lens and the lenses often need service to repair.

I believe I had some kind of virus attack. I got everything cleaned up. (I HOPE) In the process of cleaning the virus, I unintalled Firefox because it wouldn't open. Kept getting the error message that Firefox was already open and I had to close out of the sessions or restart the computer. After restarting the computer several times and not being able to find any open sessions in task manager, I uninstalled. When trying to reinstall, I get the error message "can not find archive file." I've tried downloading Firefox from cnet as well as the Mozilla site to no avail. Please help. I'm getting tired of using Chrome already!
Hello,
Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
Please report back to see if this helped you!
Thank you. -
hey all, I have been getting the "cannot get mail" error message on my iphone5 suddenly.
ive been using iphone to check two email accounts for months now, one is gmail and not troubled. the other is mail from thunderbird and i get this error message now saying it is not responding. no settings have been changed or anything, it just suddenly stopped receiving mail on my device as of Tuesday afternoon.
Does anyone have iny ideas about why? i have yet to update to the new OS7 yet, could that be it?'The installer has insufficient privileges to modify this file C:\Program Files (x86)\Common Files\Apple\Apple Application Support\Web kit.resources\inspector\Images\Spinner Inactive Selected.gif.'
That one's consistent with disk/file damage. The first thing I'd try with that is running a disk check (chkdsk) over your C drive.
XP instructions in the following document: How to perform disk error checking in Windows XP
Vista instructions in the following document: Check your hard disk for errors
Windows 7 instructions in the following document: How to use CHKDSK (Check Disk)
Select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors, or use chkdsk /r (depending on which way you decide to go about doing this). You'll almost certainly have to schedule the chkdsk to run on startup. The scan should take quite a while ... if it quits after a few minutes or seconds, something's interfering with the scan.
Does the chkdsk find/repair any damage? If so, can you get an install to go through properly afterwards? -

ihone 4s lost all contacts. I tried to restore from backup but the error message now says there is not enough room. I have deleted all the apps without making any more room on iphone. Why did contact disappear and how do I get them back?
In the simplest sense, archiving a file means making a copy that you never change and never discard. You already know how to do that.
iPhoto has built-in archival features, in the sense that it saves all versions of an image that you've modified. As long as you have adequate backups, you don't necessarily have any reason to archive an iPhoto library. If you want to delete images from the working library but still have access to them in case you change your mind, then you do need to archive those images. I don't have a specific suggestion as to how you should do that. You might post a question in the iPhoto forum. -

I have a PowerShot A495 camera. It has been working properly since I purchased about 2 years ago but recently a lens error message has been appearing on switching the camera on and it closes immediately. What could the problem and what should I do?
Fix #1: Remove the batteries from the camera, wait a few minutes. Put a fresh set of batteries back in (preferably rechargeable NiMH 2500mah or better) and turn the camera on. If that didn't work, try pressing and holding the Function or OK button while turning the camera on.
Fix #2: Remove the batteries, then remove the memory card. Then install new batteries, and turn on the camera. If you get an Error E30, it means you don't have a memory card installed, so turn it off, slip in the memory card and turn it on one last time.
Fix #3: Insert the cameras Audio/Video (AV) cable, and turn the camera on. Inserting this cable ensures that the camera's LCD screen remains off during the start process. Thus extra battery power is available to the camera's lens motor during startup. This extra power can be useful in overcoming grit or sand particals that may be jamming the lens. If the AV cable doesn't fix the lens error by itself, consider keeping this cable installed while trying fixes 4, 5, and 7 as a means to provide extra help to these fixes. But note that I DON'T recommend keeping the cable installed during Fix 6 as you may damage the AV port while tapping the camera. Reinsert the cable only AFTER tapping the camera.
Fix #4: Place the camera flat on its back on a table, pointed at the ceiling. Press and hold the shutter button down, and at the same time press the power-on button. The idea is that the camera will try to autofocus while the lens is extending, hopefully seating the lens barrel guide pins in their slots.
Fix #5: Blow compressed air in the gaps around the lens barrels with the idea of blowing out any sand or grit that may be in there jamming the lens. Other variations include blowing with a hair dryer in "no heat" setting, or sucking the gaps with a vacuum (careful with this one).
Now we're entering into the realm of potentially damaging your camera in conducting the fix. There is definitely some risk here, so take care when conducting the following two fixes.
Fix #6: Repeatedly tap the padded/rubber usb cover on a hard surface with the intent of dislodging any particles that may be jamming the lens. Other variations include hitting a side of the camera against the palm of your hand. A lot of people have reported success with this method. HOWEVER, there is also some potential for damaging or dislodging internal components with this method, such as unseating ribbon cables, or cracking LCD screens.
Fix #7: Try forcing the lens. More people have reported success with this method than with any of the other methods. HOWEVER, there's obviously some potential for damaging your camera by using this method. Variations include gently pulling, rotating, and/or twisting the lens barrel while hitting the power button. Attempt to gently straighten or align the barrel if it's crooked or twisted. Another variation includes looking for uneven gaps around the lens barrel, and then pushing on the side of the lens barrel that has the largest gap (note pushing the lens barrel all the way in is NOT recommended as it may become stuck there). While doing any of the above, listen for a click that indicates that the lens barrel guide pins may have reseated in their guide slots. If you hear this click, immediately stop and try the camera.
I found the above by using a web search engine called "Google" by typing your camera brand, model number and "lens error" hope this helps. -

Does not resolve itself.Hi Lidmar,
First, please try this: Remove the battery pack from the camera and close the battery compartment. Now Press and hold down the power button for 5 seconds. Replace the battery pack and turn the camera on.
If your camera works normally, you're ready to start shooting. If the issue persists, we recommend that you send your camera in for service. You may arrange service for your camera here.

Itunes install error message - program not found ...x64/difxinst64.exe
itunes install error message - program not found ...x64/difxinst64.exe
no problems with ITunes on Dell Inspiron Windows 7 until yesterday. ITunes version 11.0.2. iphone won't connect stating required software is not installed. uninstall and install 64 bit version of iTunes. I have 64 bit version already. I have uninstalled and reinstalled 5 times already. When re-installing ITunes get error message c:\programdata\34be82c4-e596-4e99-a191-52c6199ebf6\x64\difxinst64.exe. file does not have a program associated with it for performing this action. please install or create an association in the Default Programs control panel. iTunes install continues after the difxinst64.exe error message but then get the iphone cannot be used error message again. therefore, I can't sync my iphone with iTunes until I figure this out.
can't win for losing. had iTunes on my windows 7 laptop for 4 years. first time I've ever encountered this.I am a PC Tech and had a customer with this issue. Ran across this post in my search and ended up finding the solution on my own. The problem isn't with the iTunes software but the installer for the GEARAspi drivers. Really the issues is with the file type asssociations in the windows registry. On the system I was working on the HKCR key for .exe should point to the exefile key but pointed to nothing. To fix it create a new txt document and paste the following in (only paste what is in between the [code][/code] tags):
[code]
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\.exe]
@="exefile"
"Content Type"="application/x-msdownload"
[HKEY_CLASSES_ROOT\.exe\PersistentHandler]
@="{098f2470-bae0-11cd-b579-08002b30bfeb}"
[/code]
Now change the extension from .txt to .reg. Then right click and select merge. iTunes should now install properly. -
SFTP Receiver adapter error Message could not be forwarded to the JCA adapter
Hi Experts,
I'm needing help to solve a problem with an SFTP Receiver interface.
Before I was sending in the adapter configuration as "Direct" in Write Modus (File .txt) and now I changed to "Use temporary file" is occurring this error:
Message
could not be forwarded to the JCA adapter. Reason: 2: Moving
/ABCftp/To_XXX/140187613515701OUT_20140604-100214-622.TXT.tmp to /ABCftp/To_XXX/01OUT_20140604-100214-622.TXT failed.
Files as TXT they are being written to the SFTP however when as TMP returns this error ... would not rule SFTP server to accept different TXT files?
I also changed the namespace to "http://sap.com/xi/XI/System/SFTP" and "http://sap.com/xi/XI/System/File" but is not working.
Any help will be welcome!
tks.Hi Durga and Naveen...
I believe the problem is when the application's legacy system picks up the file because the log file got the "tmp", ie, was not formed yet ...
I changed to a directory without the intervention of the legacy application and it worked.
I'm waiting for the opportunity to modify the legacy system to capture only files with the extension TXT.
Tks All for help! -
I'm using CS6 Extended. My OS is "Windows 7 home premium.
Can no longer load video files into CS6 for edited I keep getting error message:
'Could not complete your request because the DynamicLink Media Server is not available.'
Don't know what this means. Until just now I was able to load videos without any problems. Now I'm getting this message. Any thoughts?Hi Mylenium,
upfront:
I hope I won't be marked as spam now, since I am posting on a few relevant discussions now to this topic.
However, I really would like to ask the people who have experienced this problem to see if they were able to solve it.
Now the real deal:
I posted a question in this discussionDynamicLink Media Server won't let me import video for video frames to layers anymore.
The linked discussion is a lot younger, which is why I posted there first.
I also put in information on the steps that I have tried and my computer specifications.
I am experiencing this problem for a while now and hope you and jones1351may be able to help out. -
JSF: Error Message are not getting cleared
Hi,
I am facing some problem with error messages in JSF.
Here is what I am doing
1. User submits a form, server validates and sends back the error to the client error message added to Faces Context.
2. User checks the messages, changes the input and submits. assuming everything is correct now.
3. On server, it validates and writes data to response for download using the following code.
FacesContext faces = FacesContext.getCurrentInstance();
HttpServletResponse response = (HttpServletResponse)faces.getExternalContext().getResponse();
DownloadResponse.sendDownload( response, is, fileName );
faces.responseComplete();
}4. It shows the download popup to download the file. The problem here is that error message are not getting cleared off. User can still see the error message on the screen.
It seems I am missing something in JSF req-response life cycle. Anyone please point out the mistake.SudhirMongia wrote:
4. It shows the download popup to download the file. The problem here is that error message are not getting cleared off. User can still see the error message on the screen. Wrong. The problem is that the view is not rerendered, which makes sense because you are not sending view content to the browser but your file.
Your real question probably is: how do I cause a file download and still rerender the view afterwards to show the results? To that I myself do not have the answer unfortunately, but I have seen that question come by a few times already, so doing some searches in these forums may yield you an answer. -
I have a Canon S100. The lens will not retract. I get a Lens Error message. Will shut down automatically. Restart Camera.
It is not shutting down, I cannot restart the camera.Dixic,
Please remove the battery from the camera for a few minutes, then reinstall the battery and power the camera on again. If the error is still displayed, then the camera will need to be repaired.
To start your repair process, you'll need to complete a Repair Request on our website.
