Report Designer error

I had to re install Visual Studio after a PC crash, everything seemed to go smoothly, until I tried using reports created in designer.

It now says License information for this component not found. You do not have an appropriate license to use this functionality in the design environment.

Also when calling the Report, I get a message 'Run time error '429' - ActiveX component can't create object.

I think I must have missed something out, can anybody shed some light as to how I can over come this.

Cheers.
