Activation problem Nitro 12

[Johannes Köberlein]

Hello i have problems the activation of Nitro Pro 12.

I own 5x Nitro Pro 12 and 1x Nitro 13 license. I deactivated Nitro Pro 12 on my Surface Book to switch and try Nitro 13. Now I cant activate the old license and my another Device(Surface Pro 7)

The Support website says 0 activation available on all license expect for the Nitro Pro 13(1 activation available). All my devices have their own license.

The license with the problem is 234600-xxyyzz-157011

Can you please help me.

Edit: Change to real Serial number, didn't know a moderator oversee it.
