I've downloaded and am using a demo version of Live 4.1.4 on Mac OS 9.2.2. I've tried using several serial codes I've found online to fully activate it, but even with a working serial code, you're then required to go to ableton.com/unlock and enter the challenge code that's given to you. This will then give you an unlock key to load or enter into Live. The problem is, the webpage for this is gone, there's nowhere on the Ableton website for this anymore since it's an older version. I've been looking on the web, but I can't seem to find any way around this or a crack. I'd really appreciate any help!!
