When I attempt to sign up in the free version using Paypal I get the following error: We cannot process this transaction because there is a problem with the PayPal email address supplied by the seller. Please contact the seller to resolve the problem.<br><br>If this payment is for an eBay auction, you can contact the seller via the "Ask Seller a Question" link on the listing page. When you have the correct email address, payment can be made at www.paypal.com. I've verified my email address. What else do I need to do? Thanks, Sharifah
