3. Boot with the PRAM clearing (hold Command-Option-P-R immediately after hitting the power button)

Booted up after that and the Services were back... and OmniFocus clipping was working. Looks like it's probably the caches, but I did all of those things under the instruction of the Expert who was working with me.

This worked for me.
