I just purchased GC2-DL last night from wallmart, have a cd key and all that. I went to install it put in the key, picked dir, etc, begain installing, it gets to 56% while copying gc2_intro.bik when it askes for disk 2, i put it in and click ok. I get an immediate error message simply stating an error has occured, and i get abort, or retry options. If i click retry it askes for disk 1 again, starts copying, then asks for disk 2, then errors out again, when i click abort, it pops up saying corrupt installation file and then exits. help..............
