Marias Pass X45 Heavy Haul Session Issuw

Hello all, i recently installed Marias Pass X45 into Trainz 2012 (build 61388) and i'm having a bit of issue with the heavy haul session. What happens is that after the Amtrak train over takes me at Belton, i get a message allowing me to pass the signal at danger but after that, the session breaks in that i no longer receive messages and all the junctions are all in manual control and that the coal train im meant to overtake is stopped in Essex on the line opposite the station and the helper wont couple to me and stays put by the Essex shed.

I've tried editing the session to fix the coal train but the help still remains in place, i've stood parked in the yard for a good ten minutes before exiting the session due to no movement from the helper
