"I am in no way trying to denigrate you", (immediately posts further denigrating comments).
Look, I don't know what the deal is with you here. I sensed right from your first reply that this might go badly.
I'm too old to have childish internet spats and if you look back you will see that right from the start I have shown gratitude and respect and have been conciliatory but you wouldn't let it go and you continued raising and coming back to the subject of fault and insisting on levelling that fault at me.
For someone who is here "just to help the punters" and has no vested interest in Line6 I find this very surprising. I didn't accuse you of anything, I was thankful for your help. For me the principle topic of discussion should be how to solve the problem, not trying to pin the blame for the problem on the person raising the issue. Like I said, strange and surprising.
Once again, I'm too old for squabbling so if you want another go at blaming me for all this, have at it but I don't want to say anymore or let this escalate further. I know what I did and didn't do and I am satisfied I did the due diligence to avoid any problems. End of story.
Thank you again for the time you have taken for the problem I raised, you clearly know your stuff and this expertise is much appreciated.
Now then: I have just got off the phone with Christophe at Line6 support Germany, he's a great guy and took the time to listen and understand and make very good suggestions (absolutely not implying anything in regards to you Datacommando). The upshot is-it works!
I tried again with my Mac Studio but it kept disconnecting so we tried again with the older Intel Macbook Pro and another USB cable and it worked. Neither of us could work out why. The other USB cable is perfectly serviceable. I had messed around last night for hours with the same Macbook and tried changing the file path for the backup file changed the folder level selection as suggested in another discussion here (ie select the folder not the file) but nothing worked. Today it just suddenly did but I don't care why, I'm just so happy it did.
Thank you SaschaFranck, you appreciate that I managed to get it all working before I saw your post but yes, for what it's worth, I absolutely had that file in the backups folder, I just couldn't manage to get it recognised by the editing software.
Once again a big thank you and appreciation for Datacommando, I hope no hard feelings and I hope to have further discussion with you down the line.
Cheers,
