To fix the upload problem you need to change the permissions on the e107_files/public folder to 777 too. I cant find any reason why the downloads wont work. but Im working on it....hahaha You should also upgrade.upload the latest version of the CMS as there have been some security fixes, you can grab it from www.e107.org and it's just a case of overwriting files (except the e107_config.php file) Sorry if you already know all this, just trying to be as helpful as I can!
