As mentioned if it's a new seller they may not have upgraded their account to a Premier account which they need to do in order to accept payments. You cannot accept payments with a private account in PayPal.
You may like to send a message advising they need to upgrade their account to premier if they haven't already done so to accept the payment.
Thank you all for your responses.
No not a newbie Seller. Has been registered since 2001 with over 2 thousand fb.
She still has auctions running currently.
I must admit I am pretty annoyed. Its just bad. However I was giving her the benfefit of the doubt in case something had happened.
Her dsr's for communication & postage are pretty bad .
Really appreciate all your input. 
Check the seller fb before you buy to avoid dealing with a PITA of a transaction.I really thought you had a newby seller.
I had my email account hacked & had to change after sales so this created a problem with a few sales but i did communicate with affected buyers.I had the same egg timer symbol thingy & buyer kept cancelling & repaying before i had a chance to resend the invoice with the changed the email addy.Huge PITA but started at my end,so i sent it anyway & told her not to pay at all just for her inconvenience & cos it was just too hard to get her to wait for an invoice before repayment
A seller with over 2k fb should be doing better for the buyer for whatever problem is at her end & you may be happy that the transaction doesn't go through.I would be annoyed too.
Just as an afterthought,did you pay by echeque?sometimes a buyer has no idea that this has happened & may be a game changer.ie through a PP but via bank account.Seller may not know that the buyer is unaware about an echeque taking much longer to clear.
