A couple of months ago, my Windows XP had went into temporary user mode. Not sure if this is the right term, but after a crash, I could only login on a temporary account. It also noted that any information that I saved would be removed on each start up. I ended up NEVER shutting the computer off (in a lazy attempt) to keep my files stored on the HD, until I had a power failure. Now the files that I had are gone. Is there anyway I can retrieve those files?
