Cre Loaded admin Categories.php showing Blank page

When accessing our administrative Product Catalog /Categories/Products, the page or target is blank.... any solution?

Solution:

1.) Contacted CRE Support over 4 business days ago (with CC to sales) with active support renewal #, asking for advice or direction AND HAVE YET TO RECEIVE EVEN A SINGLE REPLY. I hopped on Live support yesterday morning, and was hung up on (chat session ended) the moment I provided our domain, support renewal #. And chat was suddenly closed for the day, when I attempted to initiate another session. 

So, we're at a brick wall with CRE support? Not happy.

2.) This was suggested here http://creloaded.org/component/jmrphpbb/82/28865.html?start=0

"drm we see this problem once in a great while on a site that has lots and lots of products, and the server hosting it has kinda limited resources

Try these things

In the end file application_top_admin_cre_setting.php add the following code:
ini_set('memory_limit', '50M');

This file is located at: /admin/includes/

Next in admin/categories.php

comment out this code

/* $image_dir = $manage_image->getDirs();
$image_file = $manage_image->getFiles('');
$file_dir = '<option value="">/</option>';
foreach($image_dir as $relative => $fullpath) {
if (substr($relative, -1) == '/'){
$relative = substr($relative, 1);
$file_dir .= '<option value="' . rawurlencode($relative) . '">' . $relative . '</option>';
}
}*/

Please try the above, it may help you"

which I tried, and did not work (page remains blank)

3.) I've checked the server logs from backend and not catching any 500 errors. 

4.) We've tried access from multiple browsers, operating systems and PC's to no avail. 

5.) Session settings as attached; have not altered this. 

6.) I can confirm our php resource limit ala memory_limit is set to 64M and cannot be moved (to 128 or 256MB) unless we process a server upgrade. 

This post: http://creloaded.org/component/jmrphpbb/topic/28587.html?f=82 has jiffy state, "I contacted live support who fixed the problem in a couple of minutes, unfortunately it wasn't relayed what the issue was, but perhaps they can post the solution here."

Frustrating as this seems like it could be a quick fix and our business is more or less stalled without access to our product categories or single reply from support.
