After I installed "The Red Alert" all the maps for skrimmage were deleted or misplaced, so now i can't play skrimmage on The Red Alert or regular Red Alert 3. Can any one help me?

Delete the skirmish.ini from "%appdata%\Red Alert 3\Profiles\".

Where do I find that?

go to the Run or Search bar, and type %appdata%. then go into Red alert 3, then Profiles, then go into your profile.

Ok i found a file labeled skirmish but not a file labeled skirmish.ini, what now?

That's the file that you should delete.
