Email me your Knockhill Gp2 track file and I will see what I can do for you.
There are alot of different reasons for a converted track not to load first time.
There is alot of info about trackediting at the trackedting infomation center at this URL:
[
www.grandprix3.ch]
This site also lists all the reasons for converted tracks not loading.
If you need to see an example of my trackediting skills, check out my Kyalami 2001 and Silverstone 1999-2001 trcaks on my website:

I have converted quite alot of Gp2 tracks for people, so hopefully I will be able to help you.
