Reactivation of my facebook account

I opened a facebook account last March, and deactivated it a day later. Facebook sent a confirmation email telling me that it was deactivated and that if I wanted to reactivate at any time, all I had to do was log in to facebook with my old email address and password. I tried just recently, and it won't let me log in. How do I reactivate my account in an instance such as this? An answer would be greatly appreciated.
