I have a lens error on a camera I just purchased last month. I haven't dropped this camera. Any suggestions?

Sometimes that can happen if the camera isn't getting all the power it needs. Check your battery contacts to see if they are dirty and obscuring the connection. Use a pencil eraser to clean all the contacts. Secondly, discharge the battery completely and then charge it overnight. Discharge again. Charge overnight. This will completely setup the battery with max capacity.

Outside of that, it may be that the camera lens has been jarred out of alignment. DO NOT FORCE IT. Just cycle it on/off several times to see if the camera can work the lens back into alignment. If that doesn't work, you're going to need Nikon to take a look at it.

I've dropped my Nikon once, and it was off, but when i picked it up, the lens was out like it was on and i was going to take a picture. I havent been able to fix it.
whats wrong with it?

You've knocked the lens loose and out of alignment. The fact that you had it off and closed and now it's sticking out doesn't bode well. And I doubt it'll be cheap to repair. Even if your warranty is in force, chances are they won't cover it for impact damage. But understand that without warranty coverage the average cost of a camera repair is around $180. As such, it may cost more to repair than it is really worth. The rule of thumb is that if the estimate for repair is north of 50% what you paid for it, you're better off taking that money and buying a newer and upgraded model.
