i need CRE Loaded Expert

Currently have a website that has gone haywire. Last weeks issue was that Bluehost ended support for PHP 4 , and changed config, file to PHP5. So we needed our site to be compatible with PHP5, which we took care of last week. Today we were updating our site with new inventory that we have in store and for some reason it just added everything under one category in the back-end, and changed the title of all the products to begin with same title for every product on the back-end, but nothing displays on the actual site. Everything was moved under "Bicycle Handlebars" in the back-end by the system. We just want to reverse whatever glitch occurred in our system so that all our products will display again. pm me thanks
