Previously I had been using foobar 0.586, and it worked so well I never upgraded. I left for college, came back home and updated it, and noticed that kernel streaming no longer shows up as an output system on the same machine (Windows XP). What gives?

Relax. If you just downloaded the installer, you probably just didnt select it during the installation. Just get the zip version of the player on the homepage, and extract foo_ks from it to your FB2000 folder and just enable it in preferences.

Next time, be sure that KS is selected in "output" during the installation.

Bingo! Thanks!
