Could you change the upgrade system on macs please? I got a message telling me to install the latest update -- so I did. I was on a paid version of Arq 3, and now I'm on a trial version of Arq 4 :-/
Didn't the upgrade text explain that it was a paid upgrade? I tried to make that as clear as I could.
If you want to stick with Arq 3 you can. Delete Arq 4. Download Arq 3 (http://www.haystacksoftware.com/arq/Arq_3.3.4.zip).
Launch Arq 3.
You'll have to find your old backup set under "Other Backup Sets", select it, and click the "Adopt This Backup Set" button.
Sorry for the hassle.
Agree that this should have been presented differently - something other than the normal update mechanism, which becomes routine over time. This is a major update with a fee associated - the 'upgraded' user is presented with an 'unlicensed' copy of Arq4 and continual purchase dialogs until they get out their credit card and pay again.
People often don't read that sort of thing, and just click the "update" button. A paid upgrade probably shouldn't be available through the normal in-app updater.
