CC121 not compatible with Win8.1? Really?

It’s the same for the CMC series stuff as well, I started a thread in that section asking about it but no one from SB has bothered to get back to me.

I’d really like to know if both lines are expecting upgrades to be compatible with 8.1, seems completely stupid that they’re not, CMC is still the current line of controller and the CC121 is not exactly that old and really does deserve a swift update, 8.1 has been out a few months now.

Is 8.1 really that different to 8 or is just a case of it hasn’t been fully tested?
