After receiving a prompt for the newest Beta and clicking through it without installing, it began installation anyway. I cancelled the install before it was finished and now Photoshop doesn't show up as an external editor in Lightroom. The option to enable Photoshop as an external editor is grayed out.
**Update
Uninstalling Photoshop and re-installing fixed the issue. Thanks Adobe, for wasting my time pushing your broken Beta on me. My invoice is in the mail.
