Yeah, likewise, I got Civ IV for Xmas and installed it on my laptop, 1.52 was working fine, but I didn't bother bringing the DVD back to college. I tried updating to 1.61, but now it just tells me to insert the Correct CD. I assume the problem is cause I don't have the original copy of the DVD here, so I guess I have to wait til a no-DVD fix comes out for 1.61 to play it again...
I didn't realize the no-dvd had to match the version, is that the problem? Anyone else get it to work? thanks
