My Adobe Products are logging out every time I restart or shut down my PC. Another problem is that it is considering that I'm logged in to 3 computers at the same time even thoug it is the same computer, I only use one PC to work.
the same computer (if it supports 32bit and 64bit) probably has a 32 bit and 64 bit install listed for the same computer. that's counted by adobe as one install. but if you think there's an unrecognized computer, you can sign out from the unrecognized computer via your account, https://account.adobe.com
your log in problem is because something (eg, av, antimalware, cleaner, defragger etc) on your computer is removing or corrupting your cached login credentials.
your cached adobe credentials are stored in the OOBE folder.
Mac OS: \User\<user name>\Library\Application Support\Adobe\OOBE folder.
