OMG I CANT BELIEVE IT

I restarted rm making for one game, so like when i opened it they say "map data corrput" and all
fixable(then how) or gone for good?

Ow... That sounds bad... You could try to make a new project and copy all the MapXXX.rxdata files after you have just created maps in the new project with the same IDs. If it doesn't work, upload your entire project, I will see if I can fix the File via Hex Editor.

Here's a full in depth solution. All credit goes to the author.

the thing doesnt open blizzard, thats the problem. I even reinstalled it, no work, i can stick to xp or reinstall the exe file.
i'll see if what dt gave can help

GREAT!
All my project files are gone, so i cant do what DD told.
Good thing is that now i dont get the "cant make new project" error.
SO....

Dude, the cant make new project error is maybe because you have a folder of the same name interfering, or you're out of disk space.
