Civil3d Project dll loading but not showing commands

I am not sure why my latest .dll project is not loading on my new work PC at the moment in 2014. The dll appears to load but you can not see the custom commands. A while ago I had a similar problem with the grading plane routines but was getting an error message described here

Tomorrow I will try the fix recommended for this error and see if it does the trick.
