Get so far on track then crashes

[ron123]

I only have the btb gtr2 version and when I maily convert a btb track from rfactor to gtr2 all goes well.. it lads up you start all is ok.... when you get about a 3rd around a track gtr2 freezes then crashes???? I havent had this problem when converting rfactor tracks to gtr2 only lately on btb ones is there a parameter or something I need to change in afile for btb? all gmts are converted from rfactor to gtr2 ones etc etc so I dont know how comes you can play a 3rd of a track (4 or 5 different ones now) and then it crashes the trace file comes up with no errors...
I thought it might be my pc but gave the tracks to 3 other people and the same happens on there pc's... anyone help?
