Payment due despite an existing credit balance
My adwords account has a $350 credit balance which has been posted for roughly a year. I recently started running a few ads, which ran for 1 week, then a message appared saying 'Your ads aren't running because we haven't received your payment. Please make a payment.' The ($350) credit still exists, what payment is due, and/or how to I resolve this? Also, this is an Adword Express account which I'd like to convert to a standard Adwords account, but that's another issue.
