Can not change Version

I have purchased VDownloader Plus lifetime version, have installed the product through the link in the install instructions, I got 5.0.4191 version, it does not have Top Menu to access and insert serial number Vitzo sent to me.

On 15-10-2022 I sent a message to support in spanish explainig the problem, answer was that it was sent to spanish support, since this day I have not had any answer.

Its not the first time I have problems with VD version  see my record I hope this time I will have some help.
