When I click on File>Get Photos and Videos>From Camera or Card Reader, nothings happens. Everything was working fine until a day or so ago. No changes on the computer, it just quit working. The card reader I want to use shows in My Computer. I uninstalled and reinstalled PSE 7, thinking that doing this might solve the problem. Didn't work. I am running Vista 32 bit.
Not sure why PE will not see your camera now, when it supposedly worked in the past.
Did you try moving the files to your PC with the Camera supplied software.
If that works then use Get Media/Downloader to try and load the files off of your PC hard drive and into PE...
