Is there a beta serial for this release... I have CS5 but my serial doesn't work for Panini and I didn't see a number like the burrito release has
I found a bit of information about serial numbers on the Panini download page:
These downloads provide 30-day trial versions of Flash Catalyst "Panini" for Mac OS and Windows. You can extend the preview release by entering a valid Flash Catalyst CS5 serial number. If you own a copy of the Creative Suite 5 editions of Design Premium, Web Premium, Production Premium or Master Collection, you can also extend the use of Flash Catalyst "Panini" by requesting an extension serial number.
Though it looks like the extension serial number system isn't active until later this month.
Right... for some reason my panini release shows 'expired' and I just installed it last week, and my CS5 volume license doesn't register, I need to explore a few more of the new features...
