I assume that the Wired mouse is behaving the same way? No Left Click?

Lets try something different-

Open System Preferences ➔ TrackPad - Put a CHECK on Secondary Click. Put a CHECK on Tap to Click.

The purpose of this is to see whether we can get away without clicking but get the tasks done just by taping on the Trackpad. Single tab = Left Click. Tap with two fingers = Right Click.
