Well i have a iMac and im new with Macs so im not sure how to fix the problem. I installed Warcraft 3:Reign of Chaos and the expansion (Frozen Throne) and they both installed fine. I run Reign of Chaos fine but when i try to run Frozen Throne, it wont start up and i get a message saying "The application quit unexpectedly". Anyone have any suggestions on what the problem is?
