Okay, we have been preparing to roll out CS6 Design Standard (w/Acrobat Pro X) for the past several months (just in time for it to be obsolete! 
).
We have had a CS6 installer working fine and all the apps and Acrobat Pro X worked fine (10.1.5 is the version installed). We're deployign Mountain Lion 10.8.3 and 10.8.4 now.
Then this week, we started seeing 'registration error' messages pop up about a minute after Acrobat Pro X launches. the CS6 apps all still work and are showing as registered just fine. This is happening on new isntalls and previously isntalled systems that have worked until now.
Nothing has changed on our end.
We suspect that Acrobat Pro X is calling home and with the relase of Creative Cloud this week something on Adobe's end has changed to cause this.
We're not likely to goto Creative Cloud any time soon (the licensing model is obscene), so has anyoene else seen this happen this week due to the CC release?
Any idea how to fix it? (since it's probably on Adobe's end, hopefully the can fix it withotu us having to reengineer our deployment packages).
