Typo on common app essay?!!?

So my computer crashed the other day and I had to retype all of my essays from my hard copies. I made changes/improvements along the way content-wise except I sent it in with a typo, I put "my" instead of "me" in my first paragraph and of course as with anybody, you're more likely to miss your own typos when reading your own work because you know what should go there. So now I've sent it in to Cornell Early Decision and I'm afraid that I'll be screwed now. Is it that bad of a mistake?! I've also accidentally put the US as my county as I read it as country, now I'm freaking out since it's no game when applying to the Ivies.... =/
