Sup, i just received a used edition of Battlefield 2142, its a legal version. I put the dvd in my iMac, it showed up like normal, dragged into applications, entered code, agreed on terms then it just shuts down, when i open it from applications it wants to open but within a second it shuts down from the dock. Some spec info: iMac 21'' 3.06 GHz Intel Core 2 Duo 8Gb 1067 MHz DDR3 NVidia GeForce 9400 256 MB Its pretty new, bought it less than a year ago, so the iMac should be good. I tried things i read somewhere about installing it from a different admin account, and patching it, did all of this, nothing works. Any tips?
