So my daughter and I play Worm W.M.D. against each other and recently (as of last night) we can't seem to invite each other to a game. We aren't sure if this is a Galaxy issue as when we try to invite each other, the overlay appears and we can see our names, but we just can't finish the invite as the "Invite" button is unresponsive.

Does anyone know what's happening?

the invite overlay works from the Gog servers which are still playing up... Gog staff seam to be unaware they cut the line

question can you see each other in the global lobby?
yes = if right click and wisper works then your network is working

you will not be able to see [stats] because Gog doesn't talk to their server... no matter what marketing says

try making an account and of course do the tutorials etc
