Hula Server

Hi
Maybe somebody's using Hula server and can help me with my problem.
I installed hula on Fedora Core 5. I tried both from the rpm and  
later from source and still can't get it to send messages no matter  
what I do. The error "Unable to Create New Message" appears at the  
top of any message when I hit send. When I check the log (/var/log/ 
messages), I always find the errors I include bellow.

hulanmap[26965]: 00020037: Could not write to "" for user "admin";  
line 2306 from 0
hulanmap[26965]: 00020037: Could not write to "MAIN" for user  
"admin"; line 566 from 0
hulanmap[26965]: 00020002: Unhandled request "" for account "admin"  
from 192.168.1.1

I get the same errors for any user.
Can anyone tell me what's wrong with my hula installation and how to  
solve this problem?
Thanks,
EJ
