Question about Anno 1503

[Bernd81]

I burned Anno 1503. Then i installed the patch 1.02 and after that the crack for the version 1.02.

But with this crack i can´t start the game. So i took the crack for version 1.01 beta

Now i can start the game but after about a 3/4 hour (a dreiviertel hour ) the game crashes...

Now, is this because of the crack or because of my system?

PS: The same mistake is without patch and only with crack 1.00 too...
