My issue wasn't with activation, but my install was affected by the bug listed in this thread as I was unable to access the update server(s). This particular instance of Malware Bytes is just the free version. I have the premium version running on another PC, but that one is working fine.
I haven't tried doing any license activation on this PC. May 16th, I believe is the day I tried to run an update on Malware Bytes before doing a manual scan. At that time I was running version 3.7 and I kept getting an error that the software couldn't connect to verify my free license (or something similar to that), and also that it couldn't connect to the update server. It advised me to check my connection, which I verified was working fine. I also verified at that time that my ESET Firewall wasn't blocking the connection. Upon searching for a resolution I came across this thread. I replaced V3.7 with V3.6 and the updates started working again.
I've done the reboot since the report was made, and I've attached the System Info export as requested.
