Paullette,
I'll be moving this post to the JFBConnect 2.5 area after I post this, just so you know (instead of the JLinked 2.5 support area).
Can you tell me what's not working? What errors or issues are you encountering? What problems are you seeing on our site?
Finally, on the JFBConnect Overview page, can you check that the versions of all the features of JFBConnect are up to date? Specifically, if you're using any profile plugins, make sure that you have upgraded those as well.
Thanks,
Alex
