Reporting Services Installation Problem

Hi,

Here's the situation:
* I had an older beta (beta 1) of RS installed on a machine at an earlier time.
* Someone manually deleted the RS files on the machine as opposed to a add/remove programs operation.
* I installed the RTM Reporing Services on the machine.
* I try to author a report and get the following message:

'The located assembly's manifest definition with name 'Microsoft.VisualStudio.Shell.Interop' does not match the assembly reference.'

I have removed VS 2003 and Reporting Services, and re-installed them numerous times, but still keep getting the same error message when I try to author a report.

Can anyone help?Which OS you are using...(Please dont tell me its XP:)..u r in trouble then)
