I cant load up a map without crashing

This is what pops up when i load a map

 

A new error popped up now

 

I ran the compatibility trouble-shooter and made the game think it was running on Vista. It worked perfectly after that*.

If that doesn't work, you could have a few missing files.

*That was a few years ago. If you run the trouble-shooter, you can make it think that your computer is Vista, 7 or XP. (It only worked for one day, apparently the map files had corrupted themselves, this could be your problem.)
