For some time I have been undecided about buying into Adobe CC. The internet appears to be full of users who had CS6 (like myself) only to find that when they opted out of CC they lost use of their CS6, despite having a licence for it. I have both CS5 and CS6 on disc, with licences, and want to be able to export files to CS6 after editing in CC, as I believe CC does not like some plug-ins. Is there anybody out there who can give me a cast iron guarantee that I would not lose the use of my CS6, in the unlikely event that I would at some point opt out of CC? And, can I use CS6 alongside with CC?
