How did you delete it? With it connected to your computer and via Windows Explorer (My Computer)? Unless you used the Shift key in conjuction with the Delete key, it should have sent it to the Recycle Bin on your computer. If so, you might find a deleted copy there and be able to "restore" it.
Otherwise, it's probably gone.
