Errant Command In Routine

[GuardianofWinter]

I have an issue with an autolisp routine that was created by one of my companies clients. It is used to load our clients specific standards and menus. It worked fine in 2008 but since i upgraded to 2010 it wants to start a new menu load command after it is done processing. I don't know where the new command is coming from. I have attached the Lisp Routine, a screen of the F2 prompt with the errant command string highlighted, and the accompanying error message. If anyone can lend a hand in helping me diagnose this issue, I would greatly appreciate it.

I don't think the posted code is the source of the error. The command window shows that the posted code has gotten to the end of that posted file. So the error must be in either or LSP files getting loaded, or the MNL files associated with the CUIX files you are loading (the MenuLoad command automatically converts MNU/MNS files to CUIX).
