subscription issue

Ive been trying to sign up for the free 10 day trial for about a month now. Each time, I receive:

You have successfully signed up for a subscription to SingSnap Gold Membership For 1 Month To TheCrow2X (monthly subscription) using PayPal.

Your first subscription payment, for $0.00 USD, has already been sent to SingSnap.

Subscription Details

Date of sign up: Apr 20, 2012
Subscription Name: SingSnap Gold Membership For 1 Month To TheCrow2X (monthly subscription)
Subscription Number: S-XXXXXXXXXXXXXXXXX

Followed by a separate email that ends with:

Amount: $12.00 USD
Date of payment failure: Apr 20, 2012
Date of next payment attempt: Apr 25, 2012
Subscription Name: SingSnap Gold Membership For 1 Month To TheCrow2X (monthly subscription)
Subscription Number: S-XXXXXXXXXXXXXXXXX

when i subscribe it tells me that that it will cost nothing. the receipt email says it costs nothing for 10 days, and the failure email says that the $12.00 USD subscription failed.
