Downgrade Pearl Expert

[MathieuMH]

Hi all,

Recently I upgraded my old avolites pearl expert from v2 to v9. Unfortunately I did not know about the fact that you lose the usability of the DMX outputs in classic mode. I have a lot of jobs where classic OS is requested. So I cannot afford losing the functionality.
I found out that this is since titan v7. So I would like to go back to v6 or v6.1. Is there anybody who stil has that OS? Can you share it with me?
Is it even possible to do this? There is a big gap between v6 and v9...

Thank you for your help!
