It isn't available yet. Early versions will be posted on the forum in a few weeks.
Just out of interest: Just bought 32, and as far as I remember, I could install new licenses over the existing licenses, and when I have updated to the new version some weeks later, I didnīt have to care about the license file anymore. Has that changed? Tried to do that on 28...
Anyway - no problem for me to save the key file for some weeks, and then do it again, but was curious, if that procedure has changed.
