I downloaded a reskin from DPSimulation recently for the HST, I followed all the instructions and have the requirements but when I went to test it out, Error an error occured while trying to load the quick drive scenario popped up!
It could be the reskin or it could be the route Try the same train on a different route If that does not work then go it to a Free Roam on any route and use the Editor to place your reskin on the track
