Just a note to say that the issues seems to be due to an empty config file (this is loaded by .NET before the error handling code, so you get the nasty message instead). There is a thread myself and Haggian worked on with the solution that worked for him at:

Note: You only need the config file in the lower post, not the new exe in the higher one. Any issues with the fix either post in there or PM me.
