The latest release of this glorious software.
Go to Ableton Official site to obtain
a valid 14-days serial.
You can find this useful to recover your Live project (just an email per serial is required) and you can use it for a long time if you have more than one email address (I don't know people who have only one email...and you?) ;-)
Other releases are coming here: 5.0.1 (unlocked), 5.2 (unlocked) and 7.0.3 (original from Ableton)
