Impossible to install my new licence

Hi,

I just bought AwoCoupon and i had the licence key via mail.
I turned it permanent via my account and tried to enter it in the module (Prestashop).
Each time i enter it keeps telling me "Data does not match".
The licence i try to enter begins with : awocouponps_******************************

I'm running a prestashop 1.6.1.4

btw all my shop is running on HTTPS, i don't know if it has something to do with the error...
