Crystal Reports crashes when accessing Help or refreshing report data

I am running Crystal Reports 2008 (v12.0.0.683) on the same server as Business Objects XI 3.0. When I open a report in the Crystal Reports 2008 designer client, the client crashes without any error messages if I try to access the Help files or refresh the current report data. My report does include parameters and a subreport. I am logging onto the Windows 2003 SP2 server via a Remote Desktop connection. Any ideas?

Thanks,

Kathy
