Cannot activate FA / infinite loading bar

[mij]

I just tried coding Lane Change Assistant on my 07/20 330e with the following tools:

• E-Sys 3.30.1
  
• PSdZData Lite 4.25.12
  
• LauncherPro 2.8.2.162
  

Thanks to the cheat codes I manged to find, change and save all three entries necessary, however I always get stuck while activating the FA.
There is just an infinite loading bar, no error message. I did not try to read/save/activate in the same session, as I've read that this causes problems.
But only reading and activating the FA also leads to the infinite loading bar.
Does anyone know why and how i can get the FA to activate?
Thanks!
