Downloaded 2.48, now I'm missing scenes?

So I downloaded 2.48 on windows. When I went to load some scenes they were gone. I went to open recent, tried opening a file that was missing and there was the unable to load error. Did my files move? Thanks for the help!

Oh and I was using the test build of 2.48 before I downloaded the finished version. The only scenes that dissapeared were the ones in the blender folder. Scenes I saved in different folders were fine.
