Crash when I start a game

Hi, I unpacked the files and everithings work. Then I installed following this viewtopic.php?t=3745&p=76977
the repository and everithings work too. Then I tried (like is written there) to create a deck with deck creator and manually adding cards (I've added one card from another source because it wasn't there). When I open it whit dotp I press start and the game crashes. The icons of the folders have now an exclamation point.
How can I resolve this?
