Heyya. Three things that you might mean in your message and how to overcome these problems.
1. Do you mean that you did System Restore? Coz system restore shouldn't mess up ur music n pictures. What you can do is run a search and look for those files. They should still be there.
2. Even if you mean that you actually formatted it (an over reaction i believe, considering your problem) you can still find tons of programs around that can look for the files that you formatted. Usually, formatting just means that the computer deleted the indexing of the files, and not the actual data itself. It's akin to the computer having a map that shows where every file is. When you do a format, you just lose the map, and not the actual buildings. If you use certain programs, you should be able to get most of the buildings (data) back again (except for the ones you wrote over...).
3. Anyways, if you havent done either, try running the computer in safe mode and turn on registry mechanic again. If it made a back-up, then you should be able to use the back-up to fix everything perfectly again.
Hope this helps.
