You are correct that a number of people had their payment methods removed, or at least had to re-enter their payment methods a few months back when LL was updating their credit system.

Have you tried to re-enter your PayPal account as a payment method?  Remember, it must be "verified"...backed up by a major credit card or a Real Life bank account.  If you use a bank account, you must keep enough money in your PayPal balance to cover any bills from LL, or the transaction will fail and you'll have to register your payment method again.
