I believe there is a problem at the Adobe CC server, as my account is active and up to date. Did a message chat with a rep( not of the tech division) the other day but he could not resolve the problem. He said he was transferring me the the tech help division, but I was not forwarded(i believe) or told anything for over 5 minutes so I stopped my messaging window. Tried my Windows 8 computer same problem as on Window 7 system. Did get one program, Adobe Muse to run on windows 8 that was downloaded over a year ago and not used or updated in a year. Over the last year have not had any problem running the Adobe apps till I tried on the 28th. Had not used the Adobe apps in the last week or two.
