What does VPN DO? And how to use it?

http://en.wikipedia.org/wiki/Vpn
Or Google 'what is a vpn' or 'how to use a vpn' many people have explained this better than me.
In short it wraps your traffic in to an encrypted link to a server (normally on the internet). Then the traffic leaves that server & goes onto the public internet. It is possible for the link to reveal information about you, but a VPN can protect you on open wifi or on bad networks etc.
Sometimes the VPN terminates inside a corporate network, so users can do work at home securely.
It is similar to using https for web browsing (secure http makes traffic difficult to intercept & read).

Error message saying this device cannot be used because Apple mobile device service is not started. What does this mean and how do I start service....had these devices for over a year now??

When I tried to sync my iphone 4 and ipad in iturnes, an error message popped up saying this device cannot be used because Apple Mobile Device service is not started! What does that mean and how do I start service? I've had these devices for over a year and update and sync regularly and have never seen this message before!

I got that message yesterday. I'm new at this so don't know if this is the correct solution but it worked for me. I reset my iPod by holding the 2 buttons down until the apple appears AND I restarted my computer. After that everything worked.

I have a Nikon D600 and D800 and I shoot everything in Raw. I use Photoshop Elements 9 for processing but I have been unable to convert any RAW files to open in PSE. Says unable to parse the file. What does this mean and how do I fix it?

Since pse 9 can only use up to camera raw 6.5 and the d600 needs at least 7.3 and the d800 needs at least 6.7, you can use the
8.6 adobe dng converter to convert those files to dng copies, which then pse 9 should open.

I just purchased an extreme. I have an express. The sales guy recommended setting up a hot spot with the express and use the extreme as a base station. What does he mean and how do I do this? What are the advantages?

I just purchased an extreme. I have an express. The sales guy recommended setting up a hot spot with the express and use the extreme as a base station. What does he mean and how do I do this? What are the advantages? How do I set this up?????

I think he means to set up the main extreme as the main router or "main base station", and then use the express to "extend" the network.
You can look up the manual for your express here for more details:
http://support.apple.com/manuals/
Extend the range of your network by adding AirPort Express to your existing AirPortExtreme or AirPort Express wireless network (this is called a Wireless DistributionSystem, or WDS). "
Extending the Range of an Existing AirPort Extreme or
AirPort Express Network
You can extend the range of an existing AirPort Extreme or AirPort Express wirelessnetwork by setting it up in a WDS. Wireless computers can connect to the network andshare the Internet connection, share files, and play network games. If you connect yourAirPort Express to your home stereo, computers on your wireless network can useAirTunes to play music on the stereo from iTunes. If you connect a USB printer to yourAirPort Express, all of the computers on the network can print to it.
n Open the AirPort Setup Assistant on a Macintosh, or the AirPort Express Assistant on acomputer using Windows XP. Follow the onscreen instructions to extend the range ofyour AirPort Extreme or AirPort Express network.
Note: Extending the range of a network using WDS may reduce overall networkperformance.

When trying to download Itunes this pops up " key not valid for use in specified state" what does this mean and how can I fix it?

When trying to download Itunes this pops up " key not valid for use in specified state" what does this mean and how can I fix it? I am using a pc laptop if that makes any difference.

Try reading through this thread: key not valid for use in specified state. Possible solution involves moving the RSA folder. Rather than deleting it as aniwack suggested I'd try this:
For "Key not valid for use in specified state" errors try moving the folder RSA from C:\Users\<User>\AppData\Roaming\Microsoft\Crypto\RSA to say C:\RSA (just in case there should be a need to restore it) then try installing again. This folder appears to act as a cache and should be rebuilt automatically as required.

You need to contact iTunes support and send an email by following the link I posted.
Simply going there does nothing.

To use iCloud, you must first set it up with your Apple ID on a device with iOS 5 or a Mac with OS X Lion.

Images have ? symbol on the top right corner of the thumbnail what does this mean and how do I remove it?

Q - My images have a
? symbol on the top right corner of the thumbnail what does this mean and how do I remove it?
A - The
? symbol is used to identify a file that Lightroom can no longer access; probably because it has been moved using OS drag/drop or Move command rather than Lightroom.
Click the
? symbol will cause a small dialog will appear. This dialog will provide information as to where the file was originally located along with an option to find (Locate) it again.
As you'll quickly realise, clicking the
? symbol is fine for finding individual files that may have been relocated, but not for large numbers. There must be a better way
Look at the Folder panel (left side of Library module) and you should find that the folder/subfolder containing the files that Lightroom can no longer find are shown in Red text. It is the red text that Lightroom uses to help you identify a folder/subfolder that contains files that it has lost track off.
On the Mac you should
Ctrl-click (right-click when using two button mouse) the folder/subfolder, a pop-up menu will appear. From the pop-up menu choose the command
Locate Missing Folder, a dialog should appear. The dialog gives you access to every hard disk connected to your computer or CD/DVDs if they're in the tray. Use this dialog to navigate to the location where the folder is now located, then select this folder (not the files). Finally, press the
Choose button and allow Lightroom to do its stuff.
The method described above also applies to the PC version although the dialog is called
Browse for Folder and the
Choose button is replaced by
OK.
You can avoid getting into a situation were Lightroom looses track of your folders/subfolders by using a variation of above.
A tutorial demonstrating above can be found
Here

Hello DEstadt,
Thanks for using Apple Support Communities.
For more information on this, take a look at:
iTunes 11.1.4 for Windows: Unable to install or open
http://support.apple.com/kb/TS5376
Check for .dll files
Go to C:\Program Files (x86)\iTunes and C:\Program Files\iTunes and look for .dll files.
If you find QTMovie.DLL, or any other .dll files, move them to the desktop.
Reboot your computer.
Note: Depending on your operating system, you may only have one of the listed paths.
Uninstall and reinstall iTunes
Uninstall iTunes and all of its related components.
Reboot your computer. If you can't uninstall a piece of Apple software, try using the Microsoft Program Install and Uninstall Utility.
Re-download and reinstall iTunes 11.1.4.

I am trying to update itunes to 11.1.1.11 and i keep getting 'erreo writing to file : C\ : Config.Ms\301ded48.rfb.Verify that you have access to that directory'. What does this mean and how can i fix it?

I am trying to update itunes to 11.1.1.11 and keep getting message at the end ' error writing to file :c:\Config.Msi\301ded48.rbf.Verify that you have access to that directory'. What does this mean and how do I fix it?

I had this exact same problem just now, trying to upgrade to 10.7.
I even got that error msg when trying to UNINSTALL iTunes!
After hours of frustration trying everyone's different suggestions, I downloaded Revo Uninstaller http://www.cnet.com.au/apps/revo-uninstaller-10610875/ which solved the problem.
Use it to help uninstall iTunes and related software components in the following order and then restart your computer:
1. iTunes
2. QuickTime
3. Apple Software Update
4. Apple Mobile Device Support
5. Bonjour
6. Apple Application Support (iTunes 9 or later)
Then you can install iTunes from scratch.
Good luck
