The issue is unique to your store.. I would say that you need to check your admin configure.php file.. I believe that's where the missing "/" originates..

Other Addons
- CSS/JS Loader
- FEC
- Colorbox
- Used the straight forward install method from what I can tell

The install is failing. I tested this on a standalone localhost and had ZERO issues. It was so automatic that it was silly. This time no joy. I have verified that the file below actually exists in the proper place...but there is clearly a "/" missing when the autoinstaller is looking for the files. This happens with EVERY file not just the one below.

Code:
Warning Missing or unreadable file:/home5/radianv2/public_html/radiant_holidays/adminincludes/languages/english/extra_definitions/bmz_image_handler.php
I typed over the actual admin name btw.
