PC Boston Sprinter Scenario Planner - All Signals Stuck On Stop

Just configured a single scenario.
ACS64 with 2 coaches.. from South Station to Providence, stopping at every station. Unloaded, not a passenger service, so not need for door. Just wanted to take a ride down the route to note speed limits.
Did not configure any other traffic.
Leaving Platform, dwarf Stop signal.
Contacted dispatcher, no effect, no message.
Waited about 5 minutes.. light doesn't change.
ATC shows, restricted, 10 and ACSES
Passing signal fails scenario. Every signal on map indicates red.

So basically cannot run a scenario out of South Station. Tried with various route combination and tracks.
