I had an update come across CC for Photoshop & Dreamweaver yesterday. After applying the update I'm finding that linked smart objects are missing from my File>Place menu. Anyone else having this issue? I had them before & now they are gone. CC shows me as having no updates available. Just checked Photoshop & it's showing I'm back at 14.0.
Sounds like the updater failed and you are running 14.0.0 again.
Uninstall and reinstall.
Won't that cause me to lose a ton of settings?
No, uninstalling and reinstalling won't change your preferences at all, unless you tell it to also remove your preferences.
