Okay, I had installed Trainz 2006 on my computer and had registered my serial number at Auran's website. Then, I uninstalled Trainz 2006. Then, yesterday, I re-installed Trainz 2006. When I went to download some stuff in the Manage Content thing, the downloader wanted me to register my serial number again. I had already registered my serial number, but now I can't download stuff into Trainz because of this Can anyone help me?
