Copy and paste the following code into your page. Note the area in the tags that say
"Copy your original html center box content into this area" Remove that and add
your original page code where that text is. This should set your page back
centered.

<div align="center"> <table width="450" align="center" cellpadding="0" cellspacing="0"><tr><td valign="top"> Copy your original html center box content into this area </td></tr></table> </div>
