Failure to start 0.C-22545-g4fa09c0 6486

just started playing again after so long, started launcher, launcher asked to update to .10 so i let it. other then the launcher i have no other cataclysm items installed. so i download the game and it installs and then i click launch and the launcher closes and the game pops up, loads for a couple seconds and… this happens.

self closed, i guess? deleting EVERYTHING cata releated and DLing everything again fixed it. still not sure what caused it.
