(SEH)Exception initializing Nlog

Question

I get the error at the end when I try to start a project I'm working on from Visual Studio. It worked fine until a few hours ago. After some minor unrelated changes it stopped working when starting from Visual Studio. It works fine when run from explorer. Even old version vom revision control (where this part of the code is exactly the same and has worked without any problems) behave the same way so it doesn't seem to be a problem in my code.

The code at Program.cs:line 14 is the following:

private static NLog.Logger logger = NLog.LogManager.GetCurrentClassLogger();

Any ideas on how to solve this?
