Railworks America

Question(s)
When I open the GM GP30-UP file the only file in it is a XML GM GP30-UP Assets file. No rail vehicles, audio or anything.
Yes I own the Add-on from Steam.
Is this normal my other engine's folders have sub folders in them.
How do I add a new skin to this engine?
Thanks for any help.

I know you said .xml file, but is there any .ap file inside?

What you should be seeing if you made no modifications are a Blueprints.pak file and a GM GP30-UPAssets.ap. If you don't have that you have a problem with your D/L. If you have that you should un-zip the .ap file and then you will all the usual group of folders. If you don't have that you need to re-acquire it.

Thanks unzipping it was the problem.
