This appears to be a fatally applied update. I just downloaded and installed 3.01 today at 9pm EST and my game is now unplayable. Upon launch, the game menu consists of psychedelic white and pink boxes that flash. I can't open a game as I can't make out anything. I had been playing version 3.0 successfully as of 2pm today. Upon reading the forums, I verified the integrity of my cache, which I did.
What did you do?
Would you please fix what you've broken?
