My facebook has been hacked

Hello,
After someone tried to log on to my account from the other side of the world, I was informed by facebook, and had to confirm that it was in fact not me. I did so, following the instructions, but they have now "temporarily locked my account"
I have reset my passwords several times, yet when I try to log into my account, theres a page that comes up saying "The www.facebook.com page isn't working. www.facebook.com is currently unable to handle this request".

How long will this "locked account" be in effect? Since I now have changed the password as advised to.
