Running MonacoPROFILER on my MacBook Pro OS 10.4.11. When I restart the Mac Book I loose the Dongle and the programme tells me I am in Demo Mode only, to get the programme to respond again I must remove the Monaco Profiler and then I have to reload the programme totally. This will work until I then restart the Mac Book.
Go to USB tools and renistalled the USB driver. This has fixed the problem in all known cases.
