There is only one Neteller account allowed per Party account. I called them and they made it sound like once a Neteller account is linked to a Party account, it is linked forever. My problem was using a Neteller account that had been used on another Party account. You could try calling them and say that you've opened a new Neteller account (say you changed the currency or something like that) and you want to use that now, as you have no access to the old one.
