Deserialization failed

I am installing SSRS for the first time. I tried to create a simple report and I am getting the following error:

Deserialization failed: The type initializer for 'Microsoft.ReportDesigner.Drawing.RptStyleConstValue' threw an exception. Line 2, position 2.

Does anyone know how to fix this error?

Thanks,

Patrick
