I think the problem is, if you break the rules that way and then they give you another chance, that sets a precedent where then other people demand second chances and misuse those chances to scam people or do worse. If this was truly an honest mistake, then I'm sorry this happened, but you can always come back and start over -- just be sure you're clear on the rules and don't make special exceptions for anyone no matter how much of a rush they are in!
