Theme not updating, plugins failing to load or update

hotsos

I have the exact same problem as the one listed below, trying to update or install plugins required fails. trying to Update BEtheme fails too.  I tried deactivatiing the theme but it didnt work, also using the theme deactivation tool. Help

Previous post that is the same problem__________________________

I have bought BeTheme for www.theozeffect.com.  The Layer Slider, Revolution Slider, WP Bakery, and BeTheme Header Builder plug-ins will not install. The error message reads: 

The package could not be installed. The plugin contains no files.

Hey, this message could mean that your license key is used on more than one domain. Please use the license manager to handle your license keys: http://forum.muffingroup.com/betheme/discussion/36219/cannot-register-deregister-your-license-key-use-this-tool#latest

If you see (on our license manager) that your license key is registered on a single domain, then please disable all of the plugins and deregister that license key (through the BeTheme > Dashboard)

After that, get into the license manager once more, if the license key is still claimed - deregister it, if it’s not, register it again on your domain (through the BeTheme > Dashboard) and try to update your theme/plugins couple of times (usually it pass after 2-3 attempts) - remember, all of the plugins have to be disabled.
thanks
