[Edwin]

I setup project trigger to my new 'AProject' in cc.net. when I start 
ccnet.exe it throws exception : The project 'BProject' does not exist on 
the CCNet server.
ThoughtWorks.CruiseControl.Remote.NoSuchProjectException
But BProject really exists for a long time, Is there anyone could help me 
what's problem of my setting? Thanks
Best Regards
