TGS missions crash with sim scheduler error

I have had the TGS carrier mission installed and working for some time now, but recently, every time I try and run them, the sim loads to the 100% part but crashes with a sim scheduler fault module befor eyou can get in the cockpit.I have unistalled and re installed the missions, the saved flights and the carrier, but still get the problem.What does the simscheduler error say about whay this is happening and any ideas about how to resolev it? Thanks, mark
