New version killing your trial ?

Decided to try BTT to see if it really fit my needs and if i can have real use of it. So far i was quite happy and made the mistake to click yes on "There is a new version do you want to install it ?" or something like that.

Now it updated my version, i have BTT disabled and no ways to have it working anymore (well maybe except buying a licence maybe ?). The trial says 0 days left, but i'm sure i had lot of days left. Is it intended ? I tried to revert to previous version as offered but still no way to have it working... As user experience it doesn't make me feel that confident about the product :frowning: .

My version is now 3.560 and i have no idea what was the previous one...
