Route not showing in TS Tools.

I have purchased the SR S15 sound pack from Steam Sounds Supreme and one of the routes to run it on is called Mid Hants over the Alps This requires the route Mid Hants from Just Trains which I have. I'm having issues with some rolling stock and I have been trying to use TS tools to check it out but for some unknown reason, the route isn't showing in TS Tools. No, it isn't in the AP file format. The route Mid Hants over the alps comes from Steam Sounds Supreme and I have contacted them and they don't seem to know. When I start up one of the scenarios I still have two rolling stock missing but SSS said the route/scenarios will run without them and to press F2 etc. After a couple of messages about the scenario, I get an OOM error and CTD. Route requirements below.
