I just d/l'ed napster for beOS and all of my file requests end in either "Failed: incompatible (old client)" or "Failed: file I/O error"
Im running on a PIII 500 mhz w/ cable modem, BeOS personal edition 5, 64MB ram. This may or may not be relevant, but it takes BeOS some time to get info from the DNS that serves my cable modem. Its weird. Anyway, if you need any more info, lemme know..
