I had an e-mac! It was finished because of watching films on some website so... I called software specialist to repair it but he asked $525... It asked me to restart again and again and the cursor and keyboard freeze... Now I have a macbook with 10.5.2 and.. I played duke nukem 3d on it and the same message came.. please tell what to do... iantivirus tell that it's fine, what is that??? Hint:I opened the game within 3 sec 2 times!
