Error Upon Loading Any Drive Mode

Whenever I load up any drive mode I get an error (eg.TrainBumpSpecEmvMask.Fx) I have looked into this and the only resolution I have found is to delete a part of the "Radiomaster" file. However I don't have one of these files.
Could really use some help.
Thanks

 

Verify your game files via the Steam Client

 

I have tried this but am still getting these errors

 

Do you have any 3rd party/workshop files on your pc or is it only Steam purchased files?

 

There is 3rd party files installed yes

 

Have you reported the problem to DTG?

If it were me I would start with just TSC and Steam derived product (no 3rd party or Workshop). If it doesn't load then I would contact DTG. If it does work (most likely possibility) one of your 3rd party downloads has overwritten some key code needed to run TSC.

 

Ok I have now narrowed it down to just the AP class 68 being the issue. I have reinstalled it a few times but the error keeps coming up.

 

That is dependent on 'DTG ScotRail Class 68' - maybe reload this first then load AP68 on top?
