I cant log in into Ubuntu! Please Help!
 

Never mind i got in after restarting.

At least you marked it solved. It is a good idea, though, to leave the original question alone and reply to it when this happens. That takes your thread off the "zero reply" set, and provides more opportunity that someone else making the same mistake will find it in a search.

Have you seen this tutorial?
It will also help you in future if you edit your profile to show a distro and location.
