If I remember right Matrix never had a 1.39. Also, I would guess that if you cant save your settings that you most likely have a clone. Sometimes if you try to save your setting and you have a clone it will kill your chip also. I checked the matrix site but it looks like they removed a lot of there old versions from the site. If it still works, I would just leave it as is, or open up your PS2 and look to see just what you really do have before you think about upgrading the software so you don't kill the chip. Just my .02 cents.
