Reinstallation to Solve Minidump Problem?

I can't play multiplayer for longer than 5-7 minutes now without getting a minidump error. I heard some people solved the problem by reinstalling, so I tried to use the "repair" option during reinstall.

I was minidumped again when I began a new game after that. Has anyone had success with full uninstall and reinstallation of the game to solve the minidump problem?

I had no problems at all until 1.03
