Letters gone missing?!?!

Both med school and the SMPs require recommendation letters to be sent as part of your application. At U of I, we use a program called LEO that stores your letters and sends them to the schools you designate on the LEO website. I figured, "hey, I did this once for med school so it'll be easy for the SMP" and I sent the letters even before I submitted the application. Loyola's SMP emails me today and says that they don't have my letters yet. I check the LEO website and the UPS tracking website which both say they were received on 3/2/09. Hmmm...So I called Loyola and had them search high and low for them and they couldn't find it. I ended up spending $18 on next day shipping to re-send them my letters. I bet you anything they will find my letters tomorrow- that's how these things go, I suppose.
