Leaving Room Crash?

This just started today, and Ive done this 5 times with the same result.

Everytime I start up Crossfire, It starts fine, I join a room fine, play the game, no problems. Then, as the game finishes, the game crashes. This keeps happening, and it started without reason. Like literally 6 hours ago I played with no problems. Is anyone else having this issue, or know how to fix it?

Thanks.
