How many winters had it been sitting? What was your winterizing process? I bought the MMI 502 pump seven years ago and it has worked flawlessly under some nasty conditions. Don't despair... they are easy to take apart, inspect and service. What exactly is "frozen"? I'm assuming the bearings, but then again, I don't see how they would corrode and "freeze" if you winterized with antifreeze or even freshwater.
