I understand the logic there but the only thing that has changed is CC. I haven't installed any additional font manager on any of the systems. The only other big software I have on my laptop is the office suite.
One thing that I have thought could be causing an issue is that I do have the CS5 suite on the systems as well because I have some big projects I've been working on and I don't know if my plugins will work in CC and didn't want to find out the hard way. I was waiting until I could finish these until I uninstalled the older version.
Side note: I don't get why Adobe wouldn't have the new install serve almost as an upate to the older ones rather than ending up having multiple versions on the computer.
