Startup crash after applying two maps?

My exports folder was filled with junk, so I cleared it entirely, then applied two map packs and then started crashing on startup.
I cleared it again, but it still crashed.

Uninstall the game, then re-download and re-install it. You can also try changing your rendering system.

I'll try it. If it persists I'll tell you.
