===================
<table cellspacing="0">
<tr>
<td id="leftcolumn" valign="top">
<!-- Start left blocks loop -->
<{foreach item=block from=$xoops_lblocks}>
<{include file="iaolsXP/theme_blockleft.html"}>
<{/foreach}>
<!-- End left blocks loop -->
=====================
edit your theme.html: change left block calling from
<{include file="iaolsXP/theme_blockleft.html"}>
TO
<{include file="Cool/theme_blockleft.html"}>
Do the same for all other blocks.
If you are modifying or renaming others' themes, make sure your theme is calling the right files.
