Man, that sucks. I'm sorry. I was put on the "Alternate List" last year. The only advice I can give you is this: Talk to them very candidly about what to do to improve your application. Go deeper than the cookie-cutter, "Well, taking a couple classes would certainly help." I talked to them about specific courses of action, specific programs, courses etc. and they were very helpful. Good luck, man. Who knows, maybe you'll luck out and get in later!!
