This is really more of a VMD question (there's a mailing list for that), but 
I'll take a shot anyway.  Broken ribbons sometimes result from other nearby 
atoms getting in the way.  That is, VMD detects "bonds" based simply on a 
distance search, and sometimes it guesses wrong or sometimes there's something 
legitimately wrong with your structure.  It could simply be that there is a 
lipid atom somewhat near a protein backbone atom and it is causing the rendering 
algorithm to fail.
