.Net - "An error occurred trying to load this assembly."

Okay, here's an issue that has me completely stumped. I have a third party mixed mode (managed and unmanaged code) assembly that I'm trying to link to from Labview. I've done the usual things, such as creating a unique project file and putting the assembly in the project directory, etc, to no avail.

Using the Select Object from Assembly dialog always returns the generic "An error occurred trying to load this assembly." DebugView returns an equally unhelpful error message: "DNError: (3)." The assembly loads just fine in .Net Reflector and I can link to it and compile from Visual Studio. Fusion Viewer (FV) shows that the assembly *is* being loaded... for some reason Labview doesn't know it.

Any ideas?
