Facebook Account not working at all

Hello,

I joined Facebook a few months ago, but couldn't understand how to use it, none of the settings were configurable, it was drviing me nuts so (finally!) found out how to delete or de-activate the account. I decided to deactivate it for a while until I could get my head round how the Facebook system is supposed to work. However a few days ago I received a spam email went from a fake Facebook address, and thinking my account might have been hacked went and logged into the site (and thereby was automatically re-activated (or so I thought).

But I still am unable to "do" anything with the account profile/info. It appears to be locked somehow. I cannot edit anything, neither the profile nor privacy settings, nothing seems to be working/alterable. All I could do was change the password which I did. It would not even let me de-activate this time and got me so annoyed I thought I'd delete the account and start again by resubscribing with a different email address. But it would not even let me delete the account! and when I tried to join up for a new account on the register page, even using a different email address, it will not let me do so! Any suggestions most welcome.
