activate license key for malwarebytes premium trial

I have four days of the Premium version of MB remaining with the present Trial Version. A return email said that a Malwarebytes agent would be in contact with me, but so far none has. An email exchange with an agent of Malwarebytes fixed the problem that prevented me installing MB Premium (By getting rid of, 'The usage level has exceeded the maximum amount?) A week ago I sent an email to the same email address that fixed this former problem. I an identical problem occurred around a year ago, with a similar above mentioned MB message. None of the instruction explaining how to install my Premium version explains what to do when I get the above message ('The usage level has exceeded the maximum amount') or when the manual process of replacing the Trial Version with the Premium Malwarebytes program repeatedly fails. What the reason for this repeated failure was never given. So I tried to install Malwarebytes Premium manually according to instructions, but that effort repeatedly failed. The License Key Number is identical to the one in my Malwarebytes Account. The message after the automatic process was, 'The usage level has exceeded the maximum amount.' When I insert my License key in the License Key Box, a Green check mark appears to the right of the License Key Box. I have repeatedly failed to have my License key replace the Trial Version with the Premium version I purchased Jan. So I downloaded a Malwarebytes Premium Trial Version. After my Windows 10 failed, I reinstalled Windows 10, but lost my Malwarebytes Premium.
