Trainz Ultimate Collection lost my case with cd key
I have had this game for quite a while, and got rid of my PC, and have been using my Mac. I recently installed Windows on a BootCamp partition, and have the disk for my Trainz game, but can't find my case with the cd key anywhere. Anybody know if there is a way to be issued a new serial number, or who I would be best to contact? Thank you in advance.
