We have a few reports in SQL Server Reporting Services. For some reason when we run the report from the website, it doesn't return any data. When I run the same report from the Report Builder, it returns data.
I looked in the logs and the only errors I could find is:
ReportingServicesService!library!8!6/15/2012-08:12:33:: i INFO: Current DB Version Unknown, Instance Version C.0.8.54.

I'm not really sure why it would be a different version. It's all SQL Server 2008 R2 and I haven't made any changes to it since it's been running.
