Wrong type argument: characterp... Everywhere

[Ian Szewczyk <roamzero@gmail.com>]

I recently installed Emacs 23 after uninstalling and older version and
starting from scratch, from here
http://ourcomments.org/cgi-bin/emacsw32-dl-latest.pl and have been
getting strange errors when loading up extensions.

For example if I try to setup msf-abbrev I get this error when I startup:

Wrong type argument: characterp, 134217869

Now I thought that maybe I wasn't setting it up right, or that it
didn't support Emacs 23. But I also tried installing packages from
ELPA (http://tromey.com/elpa/install.html) and with some of them I get
characterp errors as well,

Any idea on what's goin on? Some things work and some do not. This is
the version/system info:

This is GNU Emacs 23.0.93.1 (i386-mingw-nt5.1.2600)
