Here exact the same!
I run the MB 3.3.1 premium version with lifetime license:
I suddenly, unexpected got the the warning that Malwarebytes webprotection was disabled. I tried different times to start but no succes. I also got the error:
"Unable to connect to licence Server
"
I restarted laptop more as 10 times, and after few minutes I got the error again.
I finaly de-installed Malwarebytes using the uninstall icon in the startmenu. After uninstall I restarted the system again.
I download a fresh installer from MB website, installed but now I cannot activate my license anymore!!!
So all premium features are disabled now.
Reading here that I'm not the only one with this experience: Malware bytes, what's going on? Please fix, so I can activate my valid license again!
Forgot to tell:
Just before the first trouble started I got a BSOD: my system became very slow and then BSOD. I asume all my 16GB internal memory was eaten.
