Item I sold keeps showing "PayPal processing payment" but no payment.

Hello fellow ebayers, just wondering if anyone has been experiencing this same problem.  I sold an item and for the first time it's been showing "PayPal processing payment" and it has been taking longer than 4 days.  I logged into PayPal but no payment.  The weirdest thing my other items buyers have paid with no problem.  I've tried generating another invoice but ebay doesn't let me.  Any help will be greatly appreciated.
