What software are you using? Where are you trying to login ?

Are you trying to activating the software with the serial number when you get this error??

You can get an activation error if you are trying to run the software on too many computers. Try deactivating the software on a computer that you no longer need to run the software on. See: How can I deactivate Adobe software?

You may receive an activation error if your computer has changed recently. You can't solve this problem on your own, if you've done one of the following:

• Made changes to your computer due to a crash
  • Upgraded your computer hardware
  • Replaced a hard drive
  • Upgraded the Operating System
• Gotten a new computer and old computer is unavailable

If you still need help, Contact Support.
