Yeah i got this off another post, Creative Cloud applications unexpectedly revert to trial mode | CS6, CCM I'll try it tonight. then maybe go on chat and see what they can do for me.
If nothing works and i get stonewalled it may be worth contacting a govt dept. Its worked before.
Agreed CC is bad, I get so many crashes at work and it feels extremely clunky compared with CS6 (also flash CS6 has features that were removed from CC for no apparent reason).
Time (well, 28 days now) will tell.
