Error Generating source code - Value can't be empty

bobpitt

I have two .NET Framework DLLs (v 4.0 I believe) that I am trying to generate source code for using .NET Reflector 11.1 Trial Version. For both I get the following error when clicking the "Sart" button in the export dialog:

Gathering information about objects...

Error: Value can't be empty.

Parameter name: value

0 issue(s).

1 error(s).

Failed.

What is the cause and can this be resolved?
