Error WPT "_____" Salty 747?

Hello all, I went to Simbrief and created this flight plan.
OTHH/34R MUXOP1E MUXOP DCT LUBET L934 DAVUS DCT BOXIK DCT RALKA DCT
TASMI DCT GADSI UM860 ODALI UL852 NEGEM DCT MATEL DCT ARGES DCT
ENIMA DCT ULMIN DCT NEPOT DCT EVRIK DCT BUDOP DCT PATAK DCT LALES
DCT BNO DCT PEROX DCT SODRO DCT TABAT DCT BAMKI DCT TAMEB DCT ROBEL
DCT KEMAD DCT EMBAD DCT HMM DCT RKN DCT SPY DCT PETIK L17 BODSO Y70
POL DCT BEXET DCT DOGAL NATF LOMSI N516A TOPPS DCT ENE DCT BAF Q448
PTW J48 FLASK OZZZI1 KATL/26R

I sent request in the salty 747 FMC and loaded the route but it gave me an error message " error WPT ULMIN." I try to re-do the flight plan in simbrief by omitting this waypoint but the request times out and Simbrief can’t do it. And the route is so long that I really am not going to arduously enter every waypoint in manually. I’ve gotten these errors on other flights too and it is really disappointing because I often times end up cancelling the flight because I don’t know what to do.

Anyone else running into these errors?

Thanks

I have the same issue…I cant even enter waypoints manually.
