What is the affect of "signing out of all other computers or devices"? Does this delete the software from those machines or just render them unavailable until logged in and signed out of other machines that CC is used on?

Unable to sing in on this computer or device.

The Adobe ID XXXXXXXXXX@XXXXXXXX.com has already been used to activate the software on two other computers or devices.

0 - Retry.  I have already signed out of one of them.

0 - Sign me out of all other computers or devices.
