my issue is similar to https://forums.malwarebytes.com/topic/311143-resolved-cant-activate-license-id-key-after-updating-malwarebytes/#comment-1631750
I am trying to move my lifetime licenses to newer PCs. Trying to activate subscription on the usual downloaded free trial subscription did not work..
Tried offline setup suggested by Porthos (in the linked issue) - this worked for 1 lifetime license but not another.
On the latter, it turns from red to black, but on hitting register key it says there is error with license and to contact support.
I created a ticket 4632664 but am not very hopeful of reponse (i had tried to resolved this about a year ago but ticket got auto closed saying there was no subscription registered to my email login).
So am hoping this forum will get me better resolution.
