Hi John,
Thank you so much for your fast reply.
As soon as started reading your answers, I knew that I shouldn't have to write you about my issues. All my programmed buttons are working again, all is resolved !! Stupid me šš„“.
I actually didn't remove and reinstalled FSUIPC. I always update with the installer which remove the old and add the new files files, as you discribed. So that couldn't be the issue.
About the "functions" I meant the presets, and here you are right. So I restarted how to reprogram the buttons but unexpected I saw "Select for Preset". And there I was wrong, I selected "Select for FS control". ThƔt's the reason why I couldn't find the A32NX presets. After selecting Presets, I knew that I was on the right way and within a few minutes it was all done. I only had to search to get the bat1 & 2 buttons working again. I had to select "OVHD ELEC BATTERY 1 TOGGLE" instead of "A32NX OH ELEC BAT1 TOG", same for bat2 and that's quiet confusing. Anyway all is back as before, except that I don't know how it could happen.
Best regards and again excuse me for disturbing you with my faults. You may close this topic as resolved.
Peter
