Just saying "it doesn't work" doesn't help much in troubleshooting, however..

===============

- Are you getting an error? If so, what's the error?

- Does it show up in the list, and not play?

- Does it show up in the list, and play something, but incorrectly?

- Does it say it's imported (in the list on the right side of Resource Manager), but it doesn't show up anywhere else?

- Did you try copying it manually to your project folder? If not, try that.

Hmm.. you'll have to describe your situation. I can't see your computer from here, heh..
