How can I recover my original hotmail account and still create a different one?

I have 3 hotmail accounts and wanted to create a fourth one. While logged in to my original account (the one I've had the longest) I selected the "create new account" option and wrote the name of the new account that I wanted to create. To my dismay, what I did was rename my original account with the new account's name. (That option is very misleading and should be removed from there, by the way.) I tried to re rename my account with its original name but it gives me a "name not available" message. I am freaking out because I need all four accounts, and, since that one is the original one, that's the one that gets the most daily emails. I also don't want my contacts to receive a name change message because it's just going to get very confusing when I recover the original name. Please HELP!!!!
