Yes. You must send in your resubmission no later than 37 months after the receipt date of your new, renewal, or revision application. Don’t use the day you actually submitted your original application in your calculation.
Also, your resubmission application must be submitted for the dates as listed in the appropriate funding opportunity announcement. So if you submitted a new R01 application back on February 5, 2009, you’ve still got a few days to get it in before the March 5, 2012 R01 deadline!
