Problems with CDG game..

I am in the middle of a cdg with a colleague and suddenly, I cant draw cards from the deck…I havent changed passwords or anything. Only my deck is visible (as it should be) but a right click produces nothing at all.
I’m playing Barbarossa to Berlin…
The wierd thing was it seemed to be working fine for the first few logs but now I cant draw any more cards at all

Can anyone help??
