OS Commerce : Ultimate SEO URLs Fix

Hi all, I followed the instruction to install Ultimate SEO URLs 2.2.2 latest version to my OS Commerce. Some info on my site: I am using [login to view URL], and use PHP 5.1.5 for my web. For this site, I redirect the domain to a subfolder in htdocs. Although I can see the new setup in Admin, there seem to be some technical problems: 1. When I go to [login to view URL] , it shows "The directory has no index file" 2. When I go to [login to view URL] , the site shows up but there are at least two warnings of the type: "Fatal error: Call to undefined function tep_hide_session_id()", one in catalog/includes/header (probably related to currencies) and one in catalog/includes/left_column (related to Categories) There may be other issues as well (as I can't see the content of the site now). I need one expert in OSCommerce (has done at least 20 projects in OSCommerce) to get this application WORK. I expect this job should take about 2 hours, and I am willing to pay aroung 40 USD. If there's a bidder who is qualified, can complete the job in at most 2 days, and bid less than 40 USD, the auction will be ended early. I will deposit money to escrow within 8 hours. Thank you for your interest. Good luck in bidding!
