Mmmm.. civ... one of the other things I love doing stoned, running a fake nationality in a global environment.

Get a cd/dvd/iso mounting program, find the civ 4 disc image, im assuming you have it already since you already burned it. I use Virtual Daemon Manager 4.3. Just mount the disc to a fake drive and you should be good to go.

BTW, that game might be related to your other tech problems, downlading games is soo buggy.
