Slitherine

I am in the 100YW campaign and my opponent set up a game challenge for 800 points. I accepted the game but my actual army is about 1/2 the listed max game points. I selected my army, chose the terrain but when I click play.... nothing happens. I can exit no problem it just won't launch the game. I have edited that army and saved it under the same army name 3 times, is that the problem I am having??
any help would be appreciated. Never had this problem in the past

Think we solved the problem. neither of us was up to the 800 point game size and after experimenting with some other games it turns out at least one of the players must be at the max points the game is set for or it wont launch.

Sounds like a bug....
