AutoCAD Visual LISP / AutoLISP :: Trying To Load Express Tools CUI Twice

i had my enterprise CUI working fine, and then one day it blew up and now everyone gets an error that autocad is trying to load acetmain.cui but it's already loaded. do i need to load acetmain.cui as a partial cui?  i figured that i did, but then why does acad try to load it twice?

so i have the enterprise cui loading the acetmain as a partial.  when the users log in, the enterprise cui is in loaded AS their enterprise cui in the Support Paths but then they load their own custom cui as the Main cui on their individual workstations.  THIS cui ALSO is loading the acetmain.  i think that's where the conflict is.

if that's the case, should i just give out instructions on how to remove the acetmain from their personal "custom" cui?  it seems that if i take acetmain out of the enterprise cui, that the entire menu disappears from teh individual workstations.
