trouble installing/configuring RadRails on XP

[r.g.]

Hello,

(I apologize if this isn't the right place to post this.)

I'm trying to get RadRails up and running on Eclipse 3.2 on Windows
XP.

I followed the instructions at <http://www.aptana.com/docs/index.php/
Integrating_RadRails_with_Aptana>
and the installation seemed to go smoothly. However, when trying to
follow directions for configuring it at
<http://www.aptana.com/docs/index.php/
Configuring_your_RadRails_setup>, I found that my Preferences dialog
didn't contain the Configuration page under the Rails node, nor did it
contain the Ri/rdoc page, or show the rails icon in the title bar as
image on the web page does.

Am I missing something here? Perhaps my installation didn't proceed
successfully?

I am grateful for any help you guys can provide!
