Ok, I've downloaded the demo and put some m4a's into my XXData folder and they show up in the left pane(basically following the installation guide verbatim), and clicking once will highlight the track, but I'm not able to play the track(tried crtl click also). I have the correct playback device selected, but somehow missed the exact method to set the bitrate and speed.
Go easy on me, I'm an oldtimer who just wants to try this out to see how it sounds.
I'm running Vista Business SP2 on a Lenovo T500 laptop. UAC disabled and tried "Run as Administrator."
EDIT: I'm currently reading the "Vista Users....Prepare yourselves..." thread that somehow popped up after posting.
