You say you just got it. Meaning... just purchased it? Like yesterday? Like you just took it out of the box?
If so, contact the seller or store. It's time for a refund or a repair under warranty.
If you had it for a while and it's making grinding noises when you turn the shutterspeed dial... call or email Sherry Krauter or Don Goldberg, who are both top notch Leica repair experts. Chances are they'll tell you to send the camera to them right away. If you're in the US and in the East, you may want to send it to Sherry. If you're in the Midwest and further... send it to Don (he's in Wisconsin).
Good luck!
