I am so happy now. It took me about 6 hours to figure out what the problem was. I did a little bit of searching on various trainz forums. And then I figured out why I could not download anything to trainz. The dls was not acting right but now it is. I realized, I needed to install my trainz 2006 with service pack 1 which is the one included in trainz railways. I also have sp2 but I use sp1 much more. Then, I had to install trainz classics right after I installed trainz 2006 with service pack 1. After I did all of that, I went into the trainz 2006 cmp and downloaded anything to see if the cmp would download. It did, so I checked the trainz classics cmp to see if the dls content could be downloaded and it worked. I am so happy now that my problem has been resolved.
