Explorer and Sportal give me a strange bug

I've bought Sportal for my website 1 or 2 days ago, once i set it up on my website, a strange bug append.

on Chrome and Firefox, everything is fine. (had a menu glitch, i remouved "float:left" and it got fixed)

now when i go on my website via IE, it download the html file (no extension).
i've tryed setting another template (joomla default) and it worked fine. when i go with sportal, i got the bug.

Your link is not working at this moment. Can you revert the changes you did and try IE then?
