Users not listed on ADMIN - USERS

Server Information
Servoy version R2 2.1-build 310, repository version 24

When I go to ADMIN web Page to USERS

I see this:

User list
Could not list users: null

I have ONLY one solution with two users but IM-4m not able to see them on this page.

Do I have to activate something ???

under server log in the admin page what do you see there?
Set the logging level to tracing and then go back to the user page. (and back again to logging) Do you see any entries appearing?

at first when going to log I see:

Looking for servoy.properties on C:\Documents and Settings\Default User\servoy.properties 
Loading servoy.properties from C:\Servoy\servoy.properties 
Loading - Done 
Using RMI registry on port 1099 
Looking for servoy.properties on C:\Documents and Settings\Default User\servoy.properties 
Loading servoy.properties from C:\Servoy\servoy.properties 
Loading - Done

Then I selected TRACE and hit Refresh
After that, I went to USES, saw the same

Could not list users: null

Then went back to log and saw the same thing…NO ADITIONAL lines.

Can you run Servoy with -DSTACKTRACE=true on the commandline, and then check the log file.
Please send a stack trace to me, and then I will be able to see what goes wrong.

Thanks
