For the past 6 days I have been unable to start the sim on my computer. When I click on RailWorks.exe the "Preparing to launch...." window appears momentarily and then nothing further happens. I have an 18 day old computer running Windows 10 whose specs are well above requirements. I've been running TrainSim for a long while with no problem like this until 6 days ago. Unfortunately there are no system restore points prior to the onset of the problem and as far as I can recall there were no downloads or errors during that period. I've recently discovered that Utilities.exe will not start either but other .exe files will work. I've gone through the verify files routine with Steam but no new data loads into TS2016 because it won't launch. I've tried to repurchase TS2016 but Steam won't allow it because I already own it.
Any suggestions to help me overcome this snag will be more than welcome; I really miss my daily sessions with the sim.
