Why do I get the message 'Launchpad already running' when I try and log in to Key?
The Launchpad is still open in the background.
Go to Task Manager, either Right Click on the Task Bar and select 'Task Manager' from the menu
or press the 'ctrl' 'alt' and 'delete' keys simultaneously.
If Key Launchpad is showing in the list of Applications,Highlight and select 'End Task'
