What do you mean by "restore my files"? What does that entail.
Make sure you are not grouping by anything at the top right of the song selection screen and make sure you are not filtering beatmaps by difficulty. This setting should look like this:
Try hitting F5 and if it asks to reprocess your maps, hit yes.
If that does not work, close your game, and remove the file "osu!.db" from your osu! folder. Once you restart and head to the song selection screen your maps should all reprocess. Just a note, this will mark all of your maps as unplayed which will affect that recently played grouping.

Did you actually submit the map or it was just saved locally in your computer?
Sounds like they are trying to download the original map they were editing.
