Not sure what the issue was, I'm assuming you couldn't install JFBConnect due to a permissions issue on the libraries directory.
JFBConnect shouldn't require 777 permissions on any directory, just so you know. 777 can be an insecure way to set the permissions on your directory, especially when you're in a shared hosting environment. Instead, 644 is the preferred option as long as your server is configured properly so that the 'owner' of the files is also the user that is running Apache (so that the writes can be performed properly.
Either way, I'm glad you got it going. Should you need anything else, just let us know.
