Please Please HELP! Cross Sell not working... Any ideas People?

After installing the MOD Cross Sell and even starting with the earlierst version, all files are properly installed and all the data bases are in place. However, when I click the Catalog > Cross Sell Products in admin I get the following message.

"Oops! This link appears to be broken.
Suggestions:
•Go to www.##decorativevision##s.##com
•Search https://www.decorativevisions.com for xsell products"

Additionally, in the address bar I see the following address.

http://www.decorativevisions.com/admin/xsell_products.php

This is a friend of mine website and we can not figure out what is going on with MOD. I have installed this MOD on several web sites and they all working properly.

Please please please someone give an answer. I am going nuts.

Thank you.:mellow::lookaroun:dontgetit
