Stress in Butress Threads

I have an assembly that consists of a collared metal cylinder captured by two plastic pieces joined via buttress style threads.  I can make the simulation work with no friction, but I know that’s not realistic.  When I tried to run the simulation, SolidWorks keeps telling me to reduce the coefficient of friction.  I’ve run it down to 0.05, and it still stalls.  I would greatly appreciate it if someone could take a look at the attached assembly and tell me if there is anything I could do to make it work.
