atl80.dll problems...

There seems to be a problem in my system or the game. It says that it can't locate the atl80.dll file but I can see it when I search in the crossfire folder. This happened to me twice now. Is there anyway or another way to fix this problem? I hope there is a different solution then redownloading/installing becuase my internet is slow (but my ping is 9-15 somehow) and I am planning to download other games.
