Hi,
it's really easy and simple tip. After installing demo if you want to have saving and exporting options you need to register and you can run the fully operational software. After 14 days when authorization finished uninstall demo, dl new one, register with new email and there it is. I've used Live 8 for 3 months this way and finally bought an upgrade. I know that there are cracked versions but this is a way to use this soft with legal license. Cheers! :)
