Has anyone had a problem with the MSRP addon? http://www.zen-cart.com/index.php?ma...oducts_id=1140

I just installed per the instructions, and now my product details page doesn't show up... I just get a white screen with nothing. I have triple checked the files and everything was adjusted correctly. The only think I noticed was that the instructions call for alterations of the "admin/modules/update_product.php" & "admin/modules/product/collect_info.php" files, but there isn't any "modules" file under admin unless you go into admin/includes/modules/etc.

Any input would be appreciated. I am afraid my shopping cart won't function properly.
