subscription version

In my company, we use Bonitasoft Teamwork edition.
Today, I downloaded the 7.4.1 version, and after installation, it requires a new license, but we don't want to use up one more license key just for upgrade. I could not find how to upgrade to newer version in the old Bonita bpm.
Is there a way to upgrade to newer version of Bonita without generating a new license key?
Because the server is the same, it counts as one user. So, everything's ok now.

Dear Bonita-community,

I encounter a strange behavior when using two submit-button on one page. The page has also a page-validator (That for instance only does a check on clicked button and returns always false). When I have clicked one of the two submit-buttons, the submit-button clicked stays active but then the other submit-button becomes disabled/not active. There is not detection anymore that the second submit-button is clicked.

Has anybody else found this problem and what would be the solution?

Cheers, Steven

Dear Community,

I have a problem with one of my processes; see the error I get in the log:
