Hi Bastian,

I would recommend you delete the following folder before restarting Aquamacs:

/Users/bb/Library/Application Support/Aquamacs Emacs/

There is seems to be an old package from a previous installation.

If that does not help, start Aquamacs without customizations using the function in Help -> Diagnose…
