Hi!
CassiniMetabase.xml is a Cassini application configuration file usually located in "C:\Documents and Settings\All Users\Application Data\UltiDev\Cassini" folder (non-Vista case). It's failry easy to understand and modify (please make a back up copy before editing the file).
If application configuration turns out to be not a problem, please
send us error information with execution stack and corresponding Even Log entries - we'll do our best to help you resolve the issue.
Best regards,
UltiDev Team.
