I just got my SC2 all patched and updated, and I go to do my 5 placement matches again, and 2 out of 3 times it'd crash on me, just as I was about to air raid the enemy base. I had to Windows key out and shut down SC2 in Task Manager to end it. I could move around the screen and click on stuff but nothing would happen. Fortuneately the 2 crashes didn't give me losses or I'd be super pissed right now.
Just wait until tomorrow I guess. It's not usually like this btw, this patch crashed the servers apparently.
tis two times now I've gotten just to the fighting... then freeze and crash:*( hope it will be worth the wait when release comes, cause its glitchy as all get out right now
