Hello,

I am having issues with installation. All seemed to go according to plan until the very last step when it tries to open the forum for the first time. I am getting the following YSOD:

Server Error in '/forum' Application.

Method not found: 'System.Runtime.CompilerServices.CallSiteBinder Microsoft.CSharp.RuntimeBinder.Binder.Convert(Microsoft.CSharp.RuntimeBinder.CSharpBinderFlags, System.Type, System.Type)'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
