Embed HTML page in WP Page

I have a program (SportTracks) that creates a HTML page from data in the program and updates a static page on my web site. What I would like to do is to update a WP Page. I have tried Embedit plugin, but have not figured out how to make a “stand alone” page appear in a WP page. I can only get a link to the other page to appear, and it works, but I want to have it in WP…..
Any ideas out there?
