Upgrading from 1.1.5 to 1.1.6

[kennad]

Sorry if this has been asked but here goes. I have 1.1.5 installed and want to upgrade to the newest version, (Why I do not know but I just do). I click on upgrade via the notification area, says click "here" so I do, then it brings me to package installer, where I see the abantecart_upgrade_116. When I click continue the program processes something then I get this - Fatal error = core\lib\package_manager.php on line 141. ****** I have also tried changing the file in the admin area as requested in the instruction, still nada. HELP?
