A Few Problems

I've been testing a few templates and the latest one is from Rockettheme called Afterburner. It looks great however when I go to edit an article I get this error message:

Warning: /home/drteri/public_html/sports/templates/rt_afterburner_j15/css/template.css or /home/drteri/public_html/sports/templates/rt_afterburner_j15/css/template.css.php does not appear to be a valid file. Reverting to JoomlaFCK's default styles

Also the article itself I have a picture that is right aligned however in IE8 browser it isn't correct but in Firefox it is.
