I've seen a number of posts similar to this problem, but they have been for Mac rather than PC.
I'm running Spotify Unlimited on Windows 7 Starter 32-bit Service Pack 1 and at first the problem was that Spotify would immediately crash without even opening. I did a clean reinstall and now the problem is that it crashes and closes down when I press play on any song. I get no error message.
Sorry if this is reposting, but any help would be appreciated!
