[Lifetime license issue?]

Malwarebytes 3 (MB) upgrade:   Lifetime Licenses DO NOT WORK beyond 24 hours, WILL NOT UPDATE!  I purchased 3 lifetime subscriptions to MB in 2013 and 2014.  NONE of them work with the MB version 3.  Since 4/25/2017 I have installed Malwarebytes 3 every day to do a scan on my computer.  The next morning, Malwarebytes will not update, I cannot reinstall MB over the existing program, so I uninstall MB, reboot my computer and download a new version of the program to do a scan.  I have tried all 3 lifetime program keys and id's, and none of them will update or function after 24 hours.  I deactivate the license to free - and it doesn't work either.  I have sent the support team all three of my MB license numbers - and still none of them work, beyond 24 hours.  I have spent hours attempting to fix the problem with the support team.  I have simply given up.
