Ultimate RPG File Corrupted!

Unfortunately the game I was working on (Ultimate RPG) became corrupted, and I don't have a backup file. Bummer. I have a much, much, much earlier build of the game, but it's sad to lose so much new stuff. The only data that I still have is about 1/4 of the tileset and the old sprite set. Even the sprites I posted last time got deleted.

OHRRPGCE has been good, but I think it's time to change engines, possibly to Game Maker.
