I wanted to format my pc so i set up a sync account whose email id i put was king_of_kings.afzal@yahoo.com (I dont know whether there was a mistake in it). After i formatted my laptop, i tried to sign in in sync but it says invalid username\password. then i tried to recover password from services.mozilla.com but there it said invalid email id (username). i had many saved passwords and imp bookmarks. I also have the sync key and the password(which is perfect). PLZ HElp!!

The most likely explanation is that you mis-typed your email address when you signed up for an account. If that's the case, there's nothing I can do to help; I suggest you try to find a backup of your laptop and restore your Firefox profile from there.
