I cannot get my 50D to detect the memory card

My 50D all of a sudden stopped detecting a memory card

If the card currently has any stored images I would attempt to get them off and then do an in camera low level format and retest.
Also, it is rare but sometimes the pins in the CF memory card socket can be damaged (bent usually).  Get a very bright flashlight, remove the memory card and look carefully at the bottom of the socket and examine the pins.

    Yeah, I'm having the same exact problem - It seems that the thunderbolt minidisplay port is only able to output the analog VGA signal, not the digital signal to support DVI and HDMI. This is a bug that came up after installing 10.7.1. I bought my macbook air with 10.7 on it, upgraded it to 10.7.1 as soon as I got it, so I have never been able to use hdmi or dvi with my macbook air. This is an extremely frustrating problem for me, I used HDMI on a daily basis with my PC. I have spent many hours at the genius bar running diagnostic tests so Apple can get as much information as possible to create a fix for this problem. I have been emailing tech support for 3 or so weeks now, they keep saying that they are working on a fix and it should be out soon, but 10.7.2 has come and gone and I still have no HDMI functionality with my MacBook Air!

  • I have two faults! 1, an error comes up in Ps CC 2014 "could not apply the saved panel configuration, restring to default and my tools have disappeared completely and anything ive tried I cannot get them back not even the drop down menu in 'window' helps

    I have two faults! 1, an error comes up in Ps CC 2014 "could not apply the saved panel configuration, restring to default and my tools have disappeared completely and anything ive tried I cannot get them back not even the drop down menu in 'window' helps at all. And 2, Lr everytime I load it up it gives me the option to retry or switch to and it takes a while for me to even get anywhere with it I think it has something to do with the catalogs? I've been using these programs for a few years now on a Mac...no problem but when I use a PC when I'm away coz it's the (only) comp available these happen PC's are so useless! Please can anyone help??...

    I can give a few suggestions on Photoshop CC 2014, but Lightroom is a separate forum and you should ask Lr questions there.
    First close Photoshop.
    Then start Photoshop by double-clicking on it's icon and very quickly after that, hold down the ctrl-alt-shift keys until you see the reset dialog. answer "Yes" to delete settings, and let Photoshop continue to load.
    It's tricky to do and may take a few tries, but at least it should reset Photoshop CC 2014 to defaults.

    After Photoshop Elements quit working for the second time in three months, I uninstalled it and now cannot get it to reinstall from the disc. Nothing happens when I insert the disc. All I can do is look at the folders and files and see nothing that tells me how to start the installation. Clicking "open with Auto play" gives me irrelevant options, view photos, share, etc. I'm running Windows 8. This program has worked, although buggy, for the past year.

    reinstall by clicking setup on your disk or downloading and installing,

  • It used to be that when I created a pdf from a word or publisher document, hyperlinks worked fine. Now I cannot get them to work unless the text displayed for the link is the complete address and it all appears on one line. Why?

    it used to be that when I created a pdf from a word or publisher document, hyperlinks worked fine. Now I cannot get them to work unless the text displayed for the link is the complete address and it all appears on one line. Why?

    You can print to the Adobe PDF printer, but that only creates links that Acrobat or Reader recognize as such. That is the reason for needing the entire URL on one line. It is not actually an embedded link, but one created by Acrobat on the fly. With OFFICE 2013 you have two choices: 1. create the PDF with the print to Adobe PDF and then add the links in Acrobat so that they are complete or 2. I think the WORD save as PDF or XPS will create the PDF with links, but not sure. If so, that would be the quickest solution for you, but be aware of potential problems with the MS plugin.
    Of course, the third option is to upgrade to XI which can be done with AA 9. You will probably not be eligible for a for an upgrade to whatever the next version will be.

    I changed my Apple ID and password last week.  Today I cannot get into my computer with the new password..help!

    Your Apple id password is not necessarily the same as your log-in password.
    The former is what you use to log-in to Apple services and sites. The latter is what you use to login to your computer. That does not change when you change your Apple ID password. Try the original computer login password.

  • Inserted a png PIP into my clip, can see it fine, can see it playing with the clip as expected when moving the play head manually, but cannot get it to play with the clip for preview, pleas help!

    I am sorry if my inquiry here seem dumb but I am a new iMovie user and cannot figure this out.  I inserted a png image into my video clip in the project as PIP, I can see it and move it and can also see it playing with the main clip if I move the play head manually, I can also see the PIP part only playing along with the undelying main clip if I use the Play button in the preview window when the PIP section is selected, however, for the life of me I cannot get it to play with the main clip all together for previewing the entire video via the video play button.  What happens is that the video plays normally and when the PIP section comes in, the video clip stop all motion during the duration of the PIP section and the PIP image itself is simply NOT showing.  Am I missing something really stupid here?  It seems as it the Picture On Picture is a separate clip that plays with the underlying main video clip if selected and played by itself but it is not part of the video clip and will not play with it.  What am I missing here, can anyone please help?

    The easiest way to get up and running is to convert your MP3s to MP4s (obviously there won't be a video track). The following link links to a file that was an MP3 that I converted to an MP4 using QT Player Pro. When you go to export the files, make sure you click on "Options" and then check the box for "Enable Streaming" in the Streaming tab. It should stream flawlessly using QT Player. rtsp://rhsstreamit.rih.org/testmp4/Scorpion.mp4
    Make sure you place the media to be streamed in the proper folder. You should only get a "404" message if the physical file doesn't exist.
    Good luck!

    My tennant had a Chinese friend visiting. He left for China last week but left
    D TOUCH at my place. We cannot get hold of him. The IPOD comes up with a message(in Chinese) that it is locked up with another Apple ID. I tried my Apple Id several times to no avail. I have printed out http://support.apple.com/kb/TS4515 , tried again and looks like they reffering to a " [email protected]" address that is locked up.

    You either have to enter the Apple ID and password for the person or contact the persons and have them remove it from their account
