By default AAS starts at the upper left of the desktop and if you have your taskbar set to the left side of the desktop it may be covering it up. Try moving the taskbar to the bottom of the desktop to see if AAS screen is under it, then move AAS to where you need it then move taskbar back to left if you desire. Once you close AAS it should remember the last known location.
NOTE: If you reinstall AAS you may have to redo the above steps.
