Dongle Problems

Hello, I recently decided to move to a Mac i5 from a pc. I get this message "licenser control can’t be installed, there are apps active that use the elicense control please quit all applications or restart the computer. I have done the restart which didn’t help. All licenses appear current and active on elicense account and on the dongle. Any advice would be help. Currently I am running Cubase 5 with Steinberg UR824. Waiting to received Cubase 6.5 upgrade in mail. thanks
