Activating the "Help" Module just shut my whole back end down, network wide

Team,

Went to activate the "Admin Help" module on ultimate branding and it shut down the back end of my entire network.

Will have to remove the plugin via FTP, but am sure it will not allow me to re-activate the plugin, as it will still think the settings are active.

How can I disable that part of the plugin so I can have the rest of the Ultimate branding plugin function properly?

Thanks

Rob Mc
