That message should allow you to sign in and log out all computers. Then you can do a normal log in on the computer you wish to use.
If that does not work, you can contact adobe via the contact page and ask to have all computers logged out.
Thank you. It did. I was hoping to have a place in the account where I could manage the computers but this works even if it results in more steps to go through.
And, just an added note that when you get back to the original computer where a number of apps were installed but now disconnected, some will reconnect when you sign into the control panel but others default to trial mode where you have to uninstall and reinstall them; a royal PITA. A couple changed from trial to installed by themselves as, I presume, Adobe did a scan so I'm waiting for that to happen to Photoshop like it did for Illustrator as I really don't want to do an uninstall/reinstall with all the filters, etc. I have.
The lesson: If your computer is going to fail make certain you tell it to disconnect the Adobe apps from that computer before it fails!
