Make sure You have installed the drivers for the Xskey, if that is done You should have a Control Panel inside Your System Preferences were You can see what authorizations that are active on Your Xskey. FYI. Logic 7 have those drivers built in, no additional installs are necessary. Good Luck, Janne
