Call the airline and mention that you've been rescheduled and you now feel you have a connection that's too tight to make. I've had this happen with both Air Canada and United Airlines, and both times, when I called the airline, they were happy to make some changes to my schedule to give me a more comfortable connection. (Air Canada was also willing to do this for me when my two-hour connection turned into an eight-hour connection on a flight out of JFK home; they were even willing to do it out of another airport - LGA - since I wasn't too concerned about which airport out of NYC I used.)
