You can do that from the Aquamacs Help menu->Diagnose and Report a Bug->Try Aquamacs without customizations. This starts a new instance of Aquamacs without quitting the one you are using.

I had something similar back in March.
Spelling stopped working in everything, not just Aquamacs. It turned out that the the whole OS had started turning its nose up at English (United Kingdom) [ise-w_accents] (Aspell).

Falling back to British English in System Preferences → Spelling → British English fixed it in Aquamacs and everywhere else.
I don't remember seeing John's error messages, but it is an easy thing to try.
