Bug while importing model file

[Arvind]

hi

I have imported a model file, LG_UFO. and run the following process
generate p p > x x~
I am getting the following error.
KeyError : 'PRIVATE`GetIntOrder[HC[nL]]'

The peculiarity is that initially I wasn't facing this error. But now I have made a small modification.That is, I was combing the SM lagrangian and the lagrangian of my own model for leptogluons. I wrote all the required parameters and lagrangian in seperate .fr files and i loaded them in the mathematica for obtain a UFO file. Initially they were in the same .fr file. Apart from this everything is the same.

Kindly help
Arvind
