Thanks for asking.
Here's a checklist:
1) Ensure you are using Remote Buddy version 1.11.4 in the about
dialog (I know you said you use the latest version, but it has
happened very often that users did not have the latest version even
though they said so)
2) Do you use the actual Sony PS3 BD Remote as pictured here (link
below)?

(background: I once received a report from a user who bought a
different remote, which was offered to him as "BD Remote", but
actually was a different model)
3) Check your batteries - are they fully charged?
4) Keep the Enter + Start buttons pressed for 2-3 seconds max, then
release them and give Mac OS and the remote some time to find one
another. Keeping the buttons pressed any longer resets the remote over
and over again and effectively prevents a connection to be established.
