Reporting Services Compiler Error

Hi All,
I'm trying to run a report in MRS that I've created and get the following when I debug or try to
run the report:
Error 1 [rsUnexpectedCompilerError] An unexpected error occurred while compiling expressions. Native compiler return value: ‘[BC42206] Maximum number of warnings has been exceeded.’ I
I checked the "warnings" tab, and there are none doesn't it figure?
Any ideas would be welcome.
Looking toward the weekend,

Servie Pack 2 and a hot fix package from MS.
This is a first for me and there's not much to go on.
Thanks [quote user="satya"]
What is the service pack level for RS & SQL Server in this case?
