Do you receive one of these errors when you try to sign in to, activate, or start a CC (Creative Cloud) or a CS (Creative Suite) product?
"We are unable to activate [product name]. Product activation is required to use this product..."
"Please connect to the Internet and retry."
"Either your computer is offline or the clock on your computer is set incorrectly, causing a connection error. An Internet connection is required. Please connect to the Internet or adjust your clock and try again."
Your computer could have trouble connecting to Adobe's activation servers.

What happens if its necessary to be offline for a while?
The Creative Cloud software makes a call to Adobe servers once a day to verify the account status.
If the account is in good standing (that is, payment is up-to-date) when the last call happens, the software status is refreshed to run for at least 99 days while being offline.
Note: Signing out and signing back in (while online) just before going offline for a long period ensures that the software will work for at least 99 days period without needing to connect.
The software still reminds you to connect to the Internet during this time. These reminders can be suppressed until the last 30 days, when a daily message prompts you to go online and refresh the software status.
