My question involves a driver's license issued by the State of: Pennsylvania

I have a PA drivers license. It expired September 15, 2009. I got the reminder from the DMV along with the form to send in with the fee to the the renewal papers, but completely forgot about it. I just found it in some paperwork on my desk. If I send in the fee and the renewal paperwork now, 2 months after the license is expired, 1) will they question if I've been driving all this time without a license and if so not fine me or not allow me to renew, and/or 2) will they treat this as an application for a new license?

Thank you!
