Problem with Webi to call a universe based on DSO

Hello everybody,

     I have created a universe based on DSO, I published on BO because after a I wanted create a Web Intelligence report base on, but when I try to call the universe just happened nothing... No error and not universe.. after that I tried to call the same universe on Lumira and I got a Error:  Fatal Exception Occured. The Cause was: com.bussinesobjects.corba.generic.container.proxy.internal,DependencyFailoverCallbackImpl$FailoverFatalException: Prepare FailOver Fail.

     Have you got any idea?.

Thanks a lot...
