When I installed my pioneer 16x I had to set region codes several times. I can't remember exactly but it was something like set it once for the drive once for the decoder card and once for the software. Since you have 4 tries left you might as well try one more time to set the code. See also region free tools at <A HREF="http://www.doom9.net" target="_new">http://www.doom9.net</A>
Remember if you ain't Muslim you ain't Shiite.
