Cannot run track after Export rFactor

[BravaSX]

Hellow,
Sorry about my english
I'll try to explain myself as much good.
After I built my track from A to Z, I did EXPORT to RFACTOR, after I did it, when I wanted to check the track in the game itself, I was surprised the runway can not raise the game comes out and gives me an error RFACTOR STOPPED WORKING.
Is there any way to fix this error it will not repeat itself again?
Hope you can help me, thank you.

Maybe your garage spots are located on the "air". Try to create a large terrain close to start/finish position, at least your car will be placed on the grass when you load your track.

Considering your Nickname I supose your're italian or brazilian.
