Audiophase KP1000 MP3 player

Just bought a mp3 audiophase kp1000 and i am having trouble downloading when i insert ub cord into my computer nothing

CHECK AND SEE WHAT FORMAT THEY ARE IN . SOME SONGS ARE IN A DIFERENT FORMAT WICH CAUSES THEM NOT TO PLAY AT ALL OR THEY PLAY ONCE OR TWICE BECAUSE THE FORMAT IS TRICKED INTO PLAYING ..

I bought 2 of these, and they both react the same way. I tried Media Player and WinAmp with no success, so I started dropping files to it like a USB key, and that was only partially successful. For certain files it comes up with a message about the thing disconnecting from the system (when it hasn't) and if I skip that file, it will work with another one (it's random the files it doesn't work with - nothing odd about the file or filename). Then, there's files that didn't get fully transferred, and have screwed up files / filenames, and it won't let me delete them (something about the way Windows XP is looking at the device maybe?) Any tips? And the big question - is there a web site anywhere? There is a support phone number, but I hate using 90% automated systems that end in someone I can't understand (they only speak Engrish).

Thanks.
