Perpetual License "lost"

[Matttcha]

Hello,

My name's Mattt.

I purchased a perpetual license in 2016 for PT 10, 11, 12 and 2016, but I didn't bought the annual plan after that year.

I recently had to change computer. I downloaded protools from my account, PT 12.8 which is the one I was running on my previous computer.

But I can't manage to lock the license that's still on my Ilok key. It's asking me to buy a new license.

I'm using a Macbook pro from mid 2015 with OS sierra 10.12
Ilok 2 with the license, nothing has changed on the Ilok.

I first dowloaded PT 12.8 from my account, then tried with downloading PT 11.3.2

None of these PT works... After instalation, when starting PT, it's asking me for a valid license.

Can someeone help me sorting this out ?

Thank you very much.

Mattt
