What happens if I was written a ticket for driving with a suspended license? How worried should I be about this ticket?

Last Friday I went to the DMV because I lost my license and needed to get it replaced. They told me my license was suspended due to an unpaid ticket. I got all of the information to take care of it and paid it that same day. But because I had to pay the ticket I couldn't afford to go back to the DMV to get a new copy of my license. Last night I got pulled over and was informed that my license was still suspended. I was unaware that I had to take further action to "re-activate" my license. So I was written a ticket for driving with a suspended license. I'm really worried about what this might do to me and I just wanted to find out how to handle this.
