If they do not lift the limitation, contact the attorney general of your state and report paypal for holding your money. Tell the attorney general you have shipped out all the items and that they will not release the limitation (if you did ship the items). For holding your money for 6 months, they are making interest off your money and have no right to do so.
I've read numerous amounts of times from users who have used paypal and have said usually within a week of them contacting their attorney general, paypal will let you withdraw from your account but don't expect to use that paypal account anymore.
But first call paypal and try to work out an arrangement and see if there's something you can do to lift the limitation. More than likely, they just want to confirm that you did authorize the use of your account for these transactions (has happened to me) and afterward they will lift the limitations.
