Okay here we go..I just purchased Trainz 2006 today and installed it. I fired it up tested it out and it seemed to run ok. Due to my many years of gaming I then got online to check if there were any updates, fixes, patches, etc. I also went ahead and setup an account on auran.com and registered my serial number. I then saw a link to downloads but all that did was take to a shopping cart page. I then saw the ftp link, accessed the ftp and downloaded the service pack. I installed the service pack and from that point on the game started acting very strangely. The first senario or session as you call it that I tried was to drive an Amtrak train. When the session loaded I was dumped into the middle of an open field with no train in sight in any direction. Well needless to say I never found any train and aborted the session. After that any other seesion that I loaded just took me to a light blue screen. Yup thats all there is just a solid light blue screen nothing else. Now when I load a session I get the light blue screen with a dialog box that has what looks like some kind of debug errors stating errors something like "Undefined call to xxxxxx". I then got back online and read something about the content manager. I opened CMP and went into the settings and entered my user name and password but it keeps saying that it cannot find an account or profile and I need to register my serial number WHICH I ALREADY HAVE DONE!!! Also while in my profile online I activated my FCT. But when I go into CMP it says "Querying First Class Ticket Status" and just sits there and never says yey or ney. I am assuming that it cannot verify my FCT because it cannot login to the account that I have no problem logging into online. Boy..this sure is one retarded game..no wonder it was on sale! My system is a P4 core duo 3.4ghz, 2gb DDR2, 1 250gb WD sata2, 1 200gb Samsung sata2 both running in AHCI mode, Geforce 7600GT PCI-E with 256mb, Asus P5B Deluxe motherboard all in an Antec nine hundred gamer case with an Antec 650 watt Trio True Power PSU. I don't think the system is lacking in anything as far as this game is concerned but if anyone knows of any specific compatibility issues with any of my hardware please let me know. I am going to completely uninstall and reinstall the game but I don't think it's going to help. I would just toss the game except my son is a train fanatic and it will just crush him if I can't get it to work. Any help is definitly appreciated.
