Seems weird. I can only think of the obvious things to try: double-check the spelling, try recreating the pretender, maybe send it from a different address?
Ok, I'll keep at it and see what happens...hopefully we can get our first turn soon. Its strange because there are no obvious mistakes (spelling etc.) but my pretender went in for the last game just fine.
Furthermore, my turns for the other two games I am playing have no problem.
Well, I've tried everything: different email address, new pretenders, sending it several times, sending it in lowercase, carefully checking the spelling. My pretender is indeed from the LAutgart and so on.
I will keep trying but as of now I've gotten 20 or so "game does not exist" messages.
