We don't know when the next menu is going to be released. That's why I mentioned you shouldn't go beyond your return period, because then they may not honor ANY return/replacement.
If you've tried your SD cards with previous menu versions as well, and you're using a standard Kingston or Sandisk, it should work right now, I would think.
If you want to wait, and the next menu doesn't come out BEFORE your return period expires, I would e-mail them back and demand a replacement, assuming you've tested everything, which sounds like you have
