I reinstalled my warcraft III games and when i try to play TFT, it quits unexpectedly. I'm using it on my macbook 2.4 ghz. I used to be able to play TFT before, but i unstalled it. I can play ROC fine, until i play TFT, then even ROC quits unexpectedly. What can i do. (i upgraded my mac's ram from 2 to 4)
