Glasswire Elite licence issue

Purchased a Glasswire Elite subscription on 13/11/2017 and have activated it on less than 5 computers.

I had to reformat my main gaming PC and apparently forgot to activate it when I reinstalled it, fast forward a few months and I just got the pop-up message to Upgrade Glasswire.

So I searched my email, found my activation code email, copy/pasted the code into the Activate window but it keeps saying my code is invalid.

Actually i use this licence only on 4 computers (desktop, laptop, work, virtual machine occasionaly)

Can you help me to solve it ?

Best regards
