I recently figured out how to get my old add-ons back on from TSW2 to TSW3 but there is one I can't seem to get back. I don't know why it isn't working but, I have a feeling it is because I have TSW2 collectors edition, I'm not sure how I can deal with this. But strangely I was able to download the class 313 for the same route, the same way I downloaded all the other old routes that I had.
Is that the disc version of TSW2 collectors edition? I know what to do if it's a disc https://dovetailgames.freshdesk.com/support/tickets/new use the category "Product Key Claims" and fill out the subsequent fields.
