Thank you for your help, but the last two reply's from support on this ticket have been, one - closing the ticket and two asking for a review of their service. They continue to insist if I did not buy it from their website I must have bought it from bogus reseller with a bad key. I sent them a copy of the purchase invoice from Newegg in 2013, I really don't think they were an unauthorized reseller but support ignored that and sent their automatic reply again. It seems if you did not buy from the Malwarebytes web site you must send them your key. But I can not login to my account due to my change to my email address and the new (to me) use of two level verification. This really came about through a series of events. First the failure of a program update that failed due to the programs inability to connect to the Malwarebytes sever and retrieve the new files after it had already deleted the old program files this can be seen in the logs I sent them. Second I decided to run the Malwarebytes support tool it deleted many more files and then crashed because it to could not connect to the sever, but it did decode and backup the key to a document it placed on my desktop (at this point I was happy to get that. Then I decided to do a fresh install and ran the Malwarebytes Clean Tool, This turned out to cause our current key problem because the clean program also deleted the key backup document from my desktop. I don't know who would have thought it would do that. By the way I did check my internet connection at that time and found it to be good working order.
I understand Malwarebytes paranoia about bogus keys. But I also get a feeling that they wish all of us grandfathered in perpetual license holders would just go away.
