I use it with CFS 3.1 (i think it's working with CFS 3 unpatched version too)

You must launch Tir_Attack 1.6 !
First of all launch freetrack and start tracking.
then :
Launch Tir_attack 1.6 first and CFS 3.1 after !
If you made an ALT + Tab and go to Tir_Attack 1.6 you will see data sand from CFS 3.1 ... It must be working now ....
If nothing work - I don't know - Wait for freetrack 2.2 release ...
