Yea they don't sell premium anymore and I apologize for asking keys on this forum. I didn't know we don't allow such things as like this. I think I will file a claim to Malwarebytes about this situation and see what the other end can do. Thanks.
If you want malwarebytes to sell you a key, open a support ticket with them, CALMLY explain your situation, explain how their software has been very useful over the years for protecting computers from ever evolving threats, and ask VERY VERY politely if you can purchase a one time lifetime key from them and tell them it will only be used on one computer.
Be very courteous and respectful.
People tend to listen to you and sometimes will go the extra mile if you elevate yourself above the standard entitled or pathetic attitude many people have. It's a long shot, no matter what, but you would be surprised by what some people will do for someone with class.
Good luck, and if they help you out, please don't abuse or take advantage of that. And for the love of god, don't run around forums posting that they sold you a key or gave you a massive discount on a subscription. I'm sure they get enough spam emails from people begging as it is.
