Database Interference? Bizarre issue here.

Hey there guys,
I have WordPress implemented in my site (Hi Tech Arcade(a site for the local video game store I manage), which also has a separate PHP Script running (a simple php include) called News Script Pro.

WordPress is installed on my /blog folder and I pull the posts and have them on my main page (which is a non-Wordpress site).
On that main page I also have this news script running and I’m seeming to have a bizarre issue seemingly because I have both these running?

I’ll explain.

whenever I place the code for the News Script Pro below the WordPress Loop everything loads up fine and dandy, however when I place the News Script Pro code above the WordPress Loop I seem to lose the get_author function? It just outputs Published By November 13,2010..no Published by John November 13,2010.
Completely missing the get_author call.
I’ll repeat.
This issue only happens when the News Script Pro code (which is a simple php include) is placed above my WordPress Loop call.

Is there some sort of database interference going on or something here? I’m pulling my hair out trying to figure this bizarre problem out! any input would be greatly appreciated!
