Reporting Error

Hi All, 

We are using Dynmaics Crm 2011, after installing UR 11 we face with an unreasonable problem.

All reports work with CRMAF_ , but if we set a filter that contains  [Owning User Manager = XXX] criteria this time reports gets error. 

I get the same error for all the filtered reports.It works fine with any type of filter but if i add woning users manager it crashes. Also the most interesting part is [owning user manager] only fails if it is [Equals To] type filter, i tried [begins with],[contains] etc. but "no problem". 

Is any body face something like this?

Thanks,
