First problem I had was that there was very little info. on instalation and "how to". After instalation, regestration is required, I never got past this spot, message indicated program was regestered in my name, contacted support several times and followed all their tips and and passwords, still got errors when trying to use "user name and Password", never was able to get on line, eventualy following all their instructions I was not even able to go to the site napster.com at all.
