521634 oscomm 2.2: pne issue and onemod

hi, i have an oscommerce 2.2 cart with 1 issues that need to be fixed amd 1 mod to install 1. this cart uses only a single currency. it will not set the default currency. i click "set as default" but it wont update. so the pricing in the store front shows as 0.00 and there is error message in admin that syas "no default currency set" 2. the attached security mod needs to be installed, including the section near the bottom "other files to be updated" . DO NOT do the part for UK country. the cart has been modified so the mod must be done manualy.
