Constant "Bugsplat crash" reparing

Everytime i open my client it says "Sorry! We've detected a problem with your installation. We will now attempt to repair the affected files"

This happened after i started a game. It's just constantly "reparing". It says ETA 160 mins.... 142 mins....

Then it goes up to 180 and back down to 154.

I cannot play the game. I even disabled my firewall :/

I don't know if this could be related to my recent ban.
