no registration and create creature possible

[Blackmagic]

at first, my english is a little bit horrible *g* so please don't wonder...

today i create my own adoptables-site. :D

and now ... it's not possible to register. I try it, and there comes:
"Your account has been created with the username xxx"
but no log in is possible.
"Sorry, we could not log you on with the details specified."

why that ?

and i could'nt create adoptables at the admin-tool. :(
i put the urls inside - they are good - but the list is empty

need help - urgently !

- I use beta2
