[SOLVED] Simple Press install problems

Thought I had a working forum with wp-forum but it doesnt work and it has no support.
So I decided to try Simple Press. Problem is that the plugin wants the_content in my theme template and I dont know how to put it there.

From Simple Press website:
More rarely, though not impossible, your theme page template nay be mssing a similarly necessary call - this time to the_content(). Take a look at the template and locate the call. If it does not exist we suggest that you open your theme index.php file, locate the same call in that file, note it's position and copy it across to your page template.

I found it in the functions.php but dont know how to transfer it.
Any help would be appreciated.

Thanks
