Cannot activate lifetime licence after 2.1.8.1057 upgrade

[CP3AS]

Installed new version (2.1.8.1057) from 2.1.6.1022 after constant reminders to upgrade. Did a clean install rather than installing over the top of old version as I have had problems with that in the past. Tried to activate lifetime licence (bought before Premium introduced) with ID and key. Got message saying have to be connected to the internet in order to activate licence, even though was connected (verified that). Tried using both admin and standard accounts, same message. Looks like I'm stuck with free version for the moment.  Anyone else had this problem?

When this happened to me, I noticed my date and time were wrong. I fixed this and activated with no problem.

Hello @CP3AS:

It is very disappointing to read that an activation or licensing issue is being
experienced with Malwarebytes Anti-Malware (MBAM).

The quickest way to resolve the issue is by contacting a Malwarebytes Consumer
Customer Support representative through:

https://support.malwarebytes.org/customer/portal/emails/new?b_id=6400

In the Description window, please provide as much of the following licensing
detail as possible there only:

• A brief but detailed account of the issue.
• Purchaser's name.
• Cleverbridge Reference Number.
• MBAM License ID and Key.

Thank you for your patience and understanding.
