Is there a reason some tracks work and others don't?

First of all, I'm having a blast with this sim, lots of fun. I've installed maybe 10-15 tracks and its easy, just drop the unzipped track into locations and it works right away.
That is except for a few like Bathurst and Autopolis. I unzipped them and did the same as the others tracks, yet for some reason they don't work.
The loading bar goes for a little bit then just stops. At that point the game freezes and I have to shut the program off.
I really want to see Bathurst, especially after I heard its such a great reproduction of the track.
So whats different about these tracks that the usual procedure doesn't work?

I'm using 1.21 which I downloaded in July, so would that make a difference ?

Yes, update to the latest version. I would consider making a clean install.

Hard to do that considering I'm doing it manually, so I'll have to do the updates one at a time, and I think theres 7 updates.

why not launching gsc sync???

Does GSC sync work If you don't use steam ?

Steam version is updated through Steam, non-Steam version is updated with gsc sync.
