Ok, a couple of things from this reply. It seems that someone may have highjacked his computer at some point and he took it in to be fixed and the person fixing it deleted a bunch of stuff including Trainz stuff. As many have suggested, Try doing a database rebuild and if that does not work perhaps you will need to reinstall the game. It sounds like you are missing core components of the game that Jointed Rail just uses in some of their items but don't own. As to the help desk. I have been a customer of Jointed Rail from nearly their first day and the few times I have had an issue. I sent an email and got a reply within a day or two ( usually within hours) and every single issue I have had got resolved. BUT, you must give them detailed info on what the issue is and provide details and sometimes screenshots to document the issues.Like @DARTrider suggested, a DBR might fix it. From the answer @norfolksouthern37 gave you, I understand that the assets you are having trouble with are either built-in or included with the JR downloads. If you cannot get them to work after getting helpful instructions multiple times, and they are “killing” your game, maybe something is amiss with your database? Maybe try an Extended DBR (Ctrl-DBR button)? If there is any corrupted data on your computer, there is nothing JR can do. Also, “the crap [you] got from the forum” has actually been repeated helpful answers from JR and fellow Trainzers. Give them credit for trying to help, as you have not given them adequate information or simply been thankful. In my experience, a little gratitude goes a long way!
My thoughts.
