I made this purchase on 3/2/2014.  Payed through Paypal, as I always do on this site.  Paypal and Bondware say the invoice has been paid, yet it's still marked as unpaid in my account.  I keep getting this message:

"This invoice has already been paid. For more information, please contact the merchant.  

Your purchase couldn't be completed  

There's a problem with the merchant's PayPal account. Please try again later."

 

Any help would be appreciated.
