This is an Drupal modules related problem.The original affiliates2 module is not working at all at my Ubercart site & someone has released a new version but its bugged too.Here http://www.ubercart.org/contrib/6298#comment-27047 All works fine from enabling & configuring the module to getting affiliate links but when that link is visited it shows 'Page not found' error.And with affiliate links of each product the browser just don't finds any page to show. Anyone who is willing to fix it contact me by MSN or send a pm.
