Hi!  I just downloaded the Spotify app onto my computer.  I had previously had it on my old laptop, so I had already had an account.  When I try to play music, however, it comes up with an error message that says "There is a problem with your sound card. Spotify can't play music."  This is the error message when I downloaded the app onto my laptop.

When I tried using Spotify directly from the app on Windows 8, it said that the music could not be played because my account was already being used somewhere else.  I don't know where else I would be logged in, and if it's talking about my old laptop it broke a year ago so it's not longer usable.

Does anyone know what I should do?  My friends can play my playlists on their Spotify accounts, so it's just my account that's the problem.  Or is it my computer?  I don't know.  Thanks in advance for any help you can provide!
