Yea, you can send a CD to them and request the signature when it gets there. Also, it's in the buyer protection policy that intangible goods are not covered, so just respond within the 10 days after they file a claim, and explain everything, and you should be ok. I am in the process as well of doing this. Paypal, in my opinion, if they do not protect against intangible items like that, they should just NOT allow claims to be filed against them at all. just my two pennies
