Nexus Mod Manager error: "Could not initialize Fallout: New Vegas Game Mode."

[drasafasforis]

After trying to run the game through the mod manager I kept getting an error complaining that steam does not have access to the game. I then changed the directory of Fallout nv to my root steam install in my  (C:) drive. After doing this I now receive the error specified in the title. 

 

I have verified integrity of game files

The game runs as fine as it can (crashing is normal) without the manager

I made sure that the mod manager updated its path to new vegas after changing its location. 

 

Not really sure what could be causing this, any ideas?
