Coasters don't show in simulator

Can anyone help me please? Whenever I download a new NL track from an here or anywhere else, it shows in my track file but not in my simulator. I tried totally uninstalling and reinstalling but nothing works. I have no viues or spyware so I don't know why it doesn't show when I try to ride it. When I try to open it in the editor it says, "Could not load track". Has anyone else had this problem?

where do you save the track files to when you download them?

I save them to the tracks file under nolimits

do you have track packager?

I save them to the tracks file under nolimits

You mean track folder? Are you running Vista?

I have vista and it works fine for me, so that shouldnt be a problem though I hear on some computers running vista it is.
