unfortunately, i got new batteries yesterday it started pairing again, just to NOT do it on the next second. Its driving me crazy, and I got it from the UK (me living in Chile) so return would be a long and difficult process. I would much prefer to get this one going.

EDIT it started working out of the blue. I'm guessing the batteries connection is faulty, but afeter a lot of taking batteries in-out it started working. And working great, too. I'm loving the keyboard.
