Invalid Report Source CR 2008

Im trying to preview a report from my webpage. I get Invalid Report Source error.

Also, I have an hint that it might be because of wrong references added to the project.

I also have questions regarding the framework versions for the assemblies.

for example, CrystalDecisions.Shared exists in both 12.0.2000.0 and 12.0.1100.0

the same with Engine. My website is a .NET 2.0 website.

Which is the exact reference I should use.

Any help is appreciated.

Thanks,
