It's not highly looked down on to do system restores, it's just something that hardly ever works. If you allowed your computer to compile retore points and you can use them, then do so. Nothing can happen that's worse than what you did...which I really don't know how you did this by moving a .txt file.
Btw, are you sure the data you're trying to access is opening using the correct file type? Try right-clicking and open using the correct program.
