We have tryed to upgrade the paralells from 9.3 to 9.5.2 without success.
Now, the Administrator Panel won't work anymore and we can't update nothing to solve the problem.

functionality. Administrators are advised to first acquire the appropriate
license key before continuing with the product upgrade.
Do you want to continue?
