Hi Shane. Nearly there!
I reinstalled TS12 in a new folder (kept old TS12 in original folder) and substituted my 'local' and 'original' folders for the factory ones and did a quick database repair. Contents Manager now shows all my content without the tooltip-token error! All the cab interiors download error free.
HOWEVER, although all my routes/content show in Contents Manager, the routes do not appear in 'Routes' in the new start up menu. Any ideas please to get the routes showing here please?
