Error when running report

I have configured Reporting Services on 2 servers, on one everything runs fine and reports can be generated. On the other, I get the following error when trying to run a report:
'/' is an unexpected token. The expected token is '='. Line 9, position 33.

I am not that familiar with Reporting Services so I could have made any mistake.

Any help is greatly appreciated.

FYI,
this is machine is running SQL Server 2005 Database services and Reporting Services, but also 2000 Database.

I'm not thrilled with the solution, but I have everything running now. I just recreated the Website under a different name and everything works.
