Application Crash - Can't find NWoods Assembly?

Today, after working for quite a long time, my application now crashes with the following:

I have verified that Northwoods.Go.Layout.dll is indeed in my programs folder. Also, I have not modified my license key or program name.

Any idea what I may have done to cause this?

Is this just on one system?

Is Northwoods.Go.dll in the folder? (that is a dependency of Layout)

My error… Bungled the install. Works fine now.

No problem.
