Even though I see this is solved and you won't need to file a claim with FedEx, I would like to mention what happened to me so that it can possibly benefit someone else in the same situation.
The only time I ever had any problem sending or receiving any gear was when I sold my Roland E35 arranger on ebay. The guy told me it didn't work.
To make a long story short, after FedEx screwed around for awhile, I talked to one of their representatives by phone. She told me they would not pay for the damage because it couldn't be proved that it worked when I sent it.
I told her that if they did not pay in full, I would get on the forums on ebay and tell them exactly what happened to the point that it became apparent it could lose them a lot of business and money.
With that, she changed her story and said that yes, they would pay in full, which they did.
