I have completely reinstalled msts, and completely reinstalled the Piccadilly route and this time it was stopping msts from loading at all. I've uninstalled the Piccadilly to let the rest of msts work but everytime i try and reinstall it it stops working again. Any ideas?
Sorry I lied, I'd actually forgotten to install X-Tracks by the looks of things. I had downloaded but forgotten to run the install file. Everything works perfectly now. Thanks for your help guys. Sorry!
