Why is my apple id account disabled? Please check and fix as soon as possible! thank you

We are fellow users, these are user forums, nobody on here can 'check and fix' it for you.

Try resetting its password (and then logging out and back in everywhere) : If your Apple ID has been locked - Apple Support

If that doesn't fix it contact iTunes Support in the country where you are (and which is therefore the country on the account) and see if they can/will re-enable it : http://www.apple.com/support/itunes/ww
