Acronis True image 2016 Mac, Licence problems

Hi All,

I have recently upgrade my Mavericks server to Yosemite Server.
It still had Acronis 2015 running on it, I bought a 5 pack licence for 2016. (not upgrade licence)

I had just deleted the Acronis App (to the trash), and downloaded the latest 2016 DMG, installted that to my applications, but a licence warning pops up, and i cannot enter my new 2016 licence..

Message I get, that this licence is not allowed to use to upgrade my previous 2015 edition.
Somewhere in my OSX system, the previous keys and licence are stored..

I have tryed to delete the app with AppDelete, but still no succes.
(AppDelete also deleted some plist files, and the App 2015)

Need some help please,

With kind regards,
Floor

p.s
Sry for my bad english, I'm from the Netherlands.
