Hi,
I've read that this can be caused when .NET 2.0 has not been registerd with IIS try:
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis -i
Apparently after this you may receive the following error:
'System.Reflection.TargetInvocationException' Error
The following link seems to have the answer
