An item with the same key has already been added

Trying to add some protection to a dll and I am getting this error:

[ERROR] Unknown error occurred.
Exception: System.ArgumentException: An item with the same key has already been added.

The stack trace is pretty useless and provides no context how to resolve.

I have cloned the source code in attempt to run it in debug and capture the actual error but the current solution doesn't build.

I don't expect a response as this project seems pretty dead and hasn't been updated for a while, I would contribute but if the it doesn't build from a clone it doesn't bode well.

The project builds if you pull yck1509's fork of dnlib here and place it inside your project directory. The code you're looking to fix, most likely, are lines 272 and 276 of VTable.cs.
