Payment still pending?

I ordered Object Desktop on Saturday using an AMEX gift card, but initially got a "declined" message because I tried to use it before it had fully activated.  However, when I go to check my balance, I see that there is a payment pending for it from Stardock.  I figured it may have just been a weekend thing and would process as normal today.  It still hasn't however, and claims that the transaction was authorized but is waiting for confirmation from the "merchant" (in this case, Stardock).  I can give the reference number from AMEX if needed, but I'd really like this sorted out so I can enjoy using OD.
