Enough is enough. Had to shut up this begging spree accepting Professional for free, as the temporary workaround. Let's see if support will be able to handle the issue during the next 6 months.
I got tired of this fixing out of the blue and complete lack of support. Got some concerns about data safety and security as well, cause 'not as advertised' is a bad omen. Will sort it out later.
