Going further into this error / IH code....

Code:
<div style="float:left; padding: 8px 5px;">
<h1><?php echo HEADING_TITLE; ?></h1>
<?php
if (defined('IH_VERSION')) {
	echo IH_VERSION_VERSION . ':&nbsp;' . IH_VERSION . '<br />';
} else {
	echo IH_VERSION_NOT_FOUND . '<br />';
}
?>
</div>
The "No Image Handler information found." message is just a result of checking if the version number is in the database or not, BUT the real problem is the rest of the IH page - there are no options / it's not possible to add/edit photos like previously, from this screen or the product/category page in admin.

So why would the Version number not being in the database stop the whole editing / uploadingfrom working?!
