Thanks for the reply. I did confirm that I have the "pacific_coast" folder only copied. I just downloaded it again to try it. It's still not showing in my selection of tracks for some reason. It's an odd issue for sure as other tracks/cars work just fine.I reckon you have a folder in a folder mate....
MAKE SURE you only copy the pacific_coast folder into your assettocorsa/content/tracks folder...
If you have a folder called pacific_coast_(v0.815) in your assettocorsa/content/tracks folder you've gone wrong...
Always extract mods to a temp directory (If you don't already do this) as it's safer...
and always have a look at the files and folders you have inside any folders before you copy into your install... To double check
