Multi Language Site Magento URL Redirect Problem ** URGENT **

This project is only for those who have very good knowledge of magento sites. we have "magento community" shopping cart based website. we have added a new language to site. we are facing this problem: In admin panel we changed Configuration > Web > URL > Add Store Code to Urls = YES Then on front end we choose second language that is french , it shows [login to view URL] which is ok for us. but once we click ENGLISH which is our default language then its shows [login to view URL] BUT we want it to be [login to view URL] WITHOUT /en/ As we have done all seo and backlinking on [login to view URL] so we do not want to lose all that. We want some solution if possible through admin panel, because with redirect through htaccess we afraid it will give our website negative points on google. We want this done quickly, please provide us solution in PRIVATE CHAT, so that we choose right away and finish this project today. Thank you
