PRO License is suddenly a free License?

On 12/04/2019 I purchased a PRO License for version 7.
Today I was greeted that my License is a free License and I can only sync two of my mail accounts.
I tried than to deactivate and activate the License again, but still it is shown as a free license.

What can I do to get help resolving this issue?
