gmt exporting and pivot issue

Hi guys !!

First post here !!, i´ve readed all tutorials pdf and post, but i´ve a problem exporting gmt/s to rfactor2..

1º - Always with my tire model... i export all wheel parts without problem (rim, brake disk, etc..) but when i do export the tire, the progress bar stop when it process the model normals and 3dsmax fail...

2º - In spinner, i´ve my body chassis with another body parts done (all pivots 0,0,0). Spindles, rims, brakedisk, etc in his correct position, but all suspensions parts are over the rim :S



any idea, help please ????


Thanks guys !!

edit: i use 3dsmax 2010 32

 

Bump for reason #1, getting that too.

 

Anyone find a cure for the tire export hang problem?
I am having this also.
Even with the ISI max file from the tutorial zip.
I'm on Max 2010 SP2.
Other objects export fine.
Just the tire is the problem.

Cheers
