I need help about a mod download

Hey creators of beamng can you please help me their is a mod i'm trying to download to install to my game but it won't download but it says it is i don't understand please help the mod is called
1980 Typical American Fullsize Series 1.0 and it is a addon to the Codename : oldsfullsize 1.0

 

What's exactly the problem here? In what way doesn't it download? To get the addon 100% working you have to download 2 addon files. You need to get the "oldsfullsize_oldsmobile_addon.zip" in the blue icon at the bottom of the first post.from here:http://www.beamng.com/threads/1980-typical-american-fullsize-series.29359/
And then you need to dowload the other part either at the same forum post by pressing the orange download button or press the orange download button here: http://www.beamng.com/resources/codename-oldsfullsize.1417/
If you have bad internet connection then the mod dowload may get corrupted in the middle of the download and then the mod won't work. To see if it is not corrupted then you should look if both file sizes are 26.5 mb and 188 mb respectively.

 

I already have the oldsfullsized mod on my game though

 

Wait so what is the problem?
Does the oldsmobile mod appear and spawn correctly in the game and does it have all the configs?
