newbie: org-mode error

["1kHz" <ikhwanhayat@gmail.com>]

Hi all,

I'm new to emacs (not new to computer, and a programmer actually), and
finding it very interesting to use. I'm trying to find ways to use
emacs to help me do my daily tasks.

Recently, I found org-mode and followed the tutorial from here:
http://dto.freeshell.org/notebook/OrgTutorial.html
But I've encountered some errors when marking a TODO item and while
creating a schedule item:

org-get-tags: Wrong number of arguments: #[nil "\212\301 \210n\205^K^@
\302^H!)\207" [outline-regexp beginning-of-line looking-at] 2 ("c:/
Program Files/Emacs/emacs/lisp/obsolete/ooutline.elc" . 10393)], 1 [3
times]

org-add-planning-info: Wrong number of arguments: #[nil "\301 \210\302
\206^V^@\303\304^H\305C\306\307#\206\^V^@\310\311!\207" [outline-
regexp beginning-of-line outline-on-heading-p re-search-backward "^\\
(" "\\)" nil t error "before first heading"] 4 ("c:/Program Files/
Emacs/emacs/lisp/obsolete/ooutline.elc" . 10028)], 1

I'm wondering why it refers to an obsolete file? How can I repair
this?

I'm using org-mode which comes with my installed Emacs.

"This is GNU Emacs 22.0.93.1 (i386-mingw-nt5.1.2600)
of 2007-02-02 on LENNART-69DE564 (patched)"

I'm on Windows, using EmacsW32

Thanks for your help...
