Hello I just got worms armegeddon and everytime I go to login after warmnet and then it crashes and says windows program has stopped working. I am using vista someone please try and help me out I can play offline fine.

A bit of a stab in the dark, but it could be a firewall pop-up breaking it. Try disabling your firewall, and if that works, add WA to the list of trusted programs (method varies).

Are you using the latest Beta version?
