Well I emailed the guys over at AEC, and Jake (from AEC) Kudos to you. 

This is an un official fix so your on your own. 

1st remove the Hack from AEC 

then you will have to manually edit the comprofiler.html.php 
(found in /htdocs/components/com_comprofiler) 

replace this line <input type="hidden" name="task" value="saveregisters" 
/> 

with this 

<input type="hidden" name="task" value="saveregisters" /> 
<?php 
// AEC HACK comprofilerhtml2 START 
global $mosConfig_live_site, $mosConfig_absolute_path; 
if (file_exists( 
JPATH_ROOT.DS."components".DS."com_acctexp".DS."acctexp.class.php" )) { 
?> 
<input type="hidden" name="usage" value="'. $_POST['usage'].'" /> 
<input type="hidden" name="processor" value="'. $_POST['processor'].'" 
/> 
<?php 
if ( isset('. $_POST['recurring'].' ) ) {?> 
<input type="hidden" name="recurring" value="'. $_POST['recurring'].'" 
/> 
<?php 
} 
} 
// AEC HACK comprofilerhtml2 END 
?> 

That will do the trick. 

my advice backup your comprofiler.html.php file before you get edit happy.
