I have an unusual problem. I just installed visual studio .Net. No when I try to create a new report and add a second table I get an error the an instruction that refernces a memory address could not be read. My co-worker also just installed visual studio .net and get the same error message. If I only use one table I can create and run the report. It happens when I add the second table. I can do multi table reports in version 8.5 but not in CR 9.0. I installed visual studion .Net 2003 so I could test SQL Server Rep[orting Services.
