And download from where? The download from the DLS is different from an outside site.
I have TRS2004, so the following is the basic sequence for that program.
Basically, when you download from the Download Station, it will open the Planet Auran shopping cart window. When you have added whatever items you want to download to the cart, click on the Download All button. It will then open the Download Helper. If it asks if you want to look at something, say yes and let it have fun. It will automatically load the items into Trainz. I think TRS2006 is slightly different, but that's the idea for 2004.
When you download from an outside source, the save window will open asking if tyou want to save the file or open it. Click save.
Once the download is complete, another window opens asking if you want to Open or Open File. I always click Open.
This will open the CDP icon for your new asset. Double click on the icon and Content Manager will open a window asking if you really want to open this suspicious file. Say yes and it will load the asset into Trainz.
So how does 2006 and CMP differ?
