Nothing you can do now, ebay buyer protection is good for 45 days and you are well past that. Now it is strictly between you and the seller. If it has been less than 61 days you may still leave appropriate feedback and dsr's.
If you paid with a credit card through paypal, you should check with the credit card company, some credit cards offer buyer protection beyond 45 days.
Wish my fingers would pay closer attention to what I spell correctly.
