Sent my whole UIC app yesterday, but just got an email saying it isn't finished.

Got an email saying that my app isn’t finished. I have no idea what it is- I have gone over the Common App several times, and other schools seem not to have this problem. They gave me a invitation code to set up an account at a status checking page, but when I signed up for that none of the buttons were working. Nothing was on the page except a “Welcome” and “Home” and “Options” button, all of which did nothing when I pressed them. I’m very angry and confused right now, I was pretty happy knowing everything was done with my apps. I will call them tomorrow and have sent an email, but just wondering if anyone else is in a similar situation. Thanks!

Also, tip to anyone; send your apps early like I did so you have some downtime in case the worst occurs! I have limited amounts of time right now, but hopefully just enough so they get back to me.
