Can you give us some more information on what error you are getting?
You will find the Reporting Services Logs somewhere similar to:
C:\Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\LogFiles
If you are calling the stored proc from the CRM report - are must make sure that it is callable by the CRM Service account.
