I don't like to see the countdown on the trial for the beta 5 (14 days, 13 days, 12 days)

Also the popup/startup is annoying, that's just a personal taste. I understand others don't mind.

If I click on "buy" haven't tried actually buying it,
But if I go through with it and "buy" it.. would this mean my new key would work on mezzmo 5 and I can run it without "trial phase" and thus without the popup/startup window or are the keys
we buy today not yet valid for mezzmo 5?

I really don't mind paying in advance for the unfinished product. But I do mind getting rid of the 14 day trial..
