Dunno Mary.. maybe you have to set up Imesh to use your sound card/ chip? (a bit rubbish Imesh must be if so)
A waste of time really if you've uninstalled Kazaa to get Imesh instead, as you probably have even more spyware now, especially if you never used Adaware, so probably a step backward, and you'd have more than likely been better off with just keeping Kazaa lol
