Sorry but I believe you was already preparing these circuits and so I didn't disturb with my problems.
I like play to GP4 following the same sequence of real Formula 1 and then I am searching for Sochi (Russian GP) and Baku.
For Sochi I have the correct GP4 files (not beautiful track) but for Baku no.
Can you help me in transforming files (see the Jumbomail)?
