have this interactive multimedia cd with songs (.wav), pictures and lyrics; it works on every pc, even under win 98, until now - when i insert cd into drive, it's interface is properly displayed, but when i try to play a song, a message appears "no wave device is installed that can play files in current format..."; still, this pc's xp pro plays system wave files. troubleshooter doesn't help, reinstalling sound card drivers neither, copying files from the cd to hdd is worthless...
