To start of with, I really appreciate anyone who reads or answers this. I am planning on making a personal route, and for it I was going to get some Jointed Rail Burlington Northern units. In the past, I have not bought any payware and only downloaded freeware. Before doing this I have some questions. If you are going to answer a question, please tell me what question you are answering. First, in the past, when downloading freeware, eventually a red stop sign with a spider in it appears. Something about script exceptions. My questions are, what is the script exception and how do I prevent it? Secondly, when the script exception is present, usually something stops working right (For example, I don't know what I did, but the script exception popped up, and then my Portals would not work in my session.). Because of this, I have to re-install my Trainz 12 software. When I do this, everything resets. The question is, if I reinstall Trainz, for the payware, do I just download it again, or is there some code that I need from Jointed Rail since it's payware?wavas asdasdd ssa
