Not been on for awhile but I'm back

I use Facebook and all of asudden last week its decided not to let me in using my email address and password.
Id tried resetting my password-but got no email to reset it.
I emailed Facebook and explained the problem and got reply saying they would get back to me,but they haven't.

I've checked everything firewall,cache,cookies etc

But my friend in england can login using my email and password no problem

Has anybody any idea what's going on, because we have run out of them
