emergency! mistake on app!!

I submitted my USC application online on dec 9 (the deadline is dec 10) and because the server was so clogged the last few weeks, I didn’t have a chance to double-check to see if I made any mistakes on my course listing page (for all those who applied to usc online, you probably understand where i’m coming from; it literally took about ten minutes to load, and it lagged horribly once it did). Anyhow, I logged on the application server again today just to check and see if I made any mistakes, and it turns out that my course listings for 12th grade was gone, and in its place was my course listing for 11th grade!! What can I do about this problem? Its past the scholarship and CNTV app deadline…do you think they would let me correct the mistake if I called them or sent them a letter? I’m getting a little desperate here =(
