Ok, i figured it out, nevermind any of my posts. Here was the problem.

So, I backed up my site and moved it to another host.

What happened was my site has the old "Cross Sell Plus Advanced Sell Combo" here http://www.zen-cart.com/downloads.php?do=file&id=1364

I forgot I was using that version and tried to load the new version called "Cross Sell Advanced" here http://www.zen-cart.com/downloads.php?do=file&id=400

DONT DO THAT!
