is there another pluggins that allow login with facebook?

ultimate facebook is not working with my site. my app is live and working well. when i use the log in with facebook it show on my site that i am online but not give me access to the back end of the site. it shows the admin is log in and show my site , my activity and my friends options but not the back end like when i usually log in with my user name. and when i go to ultimate facebook setttings , the app ID is connected correctly and the area for the token look like its still loading . is it because of buddy press or not compatible with buddy press? or is it not compatible with my network? it seems no matter support request i send in , i get no response. is there another another pluggin out there that allow log in with faceboo anybody pls?
