Ted, John, WarpD,
I have a problem with the same flight Plan - KLAS-KLAX BOACH6.HEC RIIVR2
Except Im getting a "Data Load 264 Error" in the Perf Init Page.
Navigraph AIRAC 1606
FSUIPC Licensed 4.949
Hope this helps as failure is different from those previously reported with this issue.
Monitoring the situation.
