[Serusers] registrations fails?

[daryl]

folks, this is a probably another stupid newbiew quiestion, but i've tried
to do my homework and i'm still stumped. here's what going on: i have
a ser server running using mysql. there are three subscribers defined
in the mysql ser database. this all seems to work ok. i can even login
via serweb and see the users i expect.

the problem is i am unable to register as any of these users. i have tried
using various clients and finally tried sipsak, which looks like a great 
tool.
the output form sipsak follows. if anyone can help me i sure would 
appreciate
it. i'm feeling a little dense right about now...

thanks, and best regards,

daryl
