Thanks for posting back Elliott! Wow, a new company I never heard of making audio cards--amazing! Live and learn.
On the XP--we are hearing Feb. or Apr. 2014 for the End-of-XP support date. Of course that has been pushed back before and probably will be again, as XP has the largest number of worldwide users of any Windows version in Microsoft's illustrious history. BTW, that means no more paid tech support on phone, no more XP media replacements, but not download of legacy drivers, service packs, tech articles in MSDnet, and developer kits. Our Windows Forum leader has some posts here about that if you're interested you can read the sticky he has in Windows XP forum I think. He works very closely with the Microsoft people. You have a few more months then to get things you need or upgrade to newer Windows versions etc.
Best of Luck!
