I'd say the gamedevelopper knows better what he's talking about, right?
I don't think that you've read the thread very careful. The people are complainig about the mini-image every time when a patch was out and a crack wasn't quickly released.
You can see what was the problem with the crack 1.0. It wsn't the crack with problems, but the game was that buggy. You can also see some of the confirmations of the v1.1 and 1.2 cracks working in this thread. But I guess reading 6 pages is hard.
And as a side question? What about trying the DVD and check if your videocard does meet the minimum specs? Without the crack, just insert the DVD in drive and see if the game starts without a crack. Then we can talk if there is a problem with the crack or not.
