MY MULTIPLAYER HAS BEEN DISABLED! HELP!

My cracked copy fs2004 worked fine on multiplayer for ages untill i installed the 9.1 update, now when i go into the main menu, the multiplayer button isnt clickable and also during a flight, the multiplayer button on the file menu isn't clickable!

i tried re-installing the game- still an illigal copy, and multiplayer still didnt work. then randomly yesterday it began to work- but today it has stopped again.

PLZ PLZ PLZ PLZ PLZ SOMEONE HELP ME!!!!!!!
thanks- andy (cheekytrolly@hotmail.com)

1- If you have Windowblinds by Stardock (program) delete it.
3- It's illegal and something is corrupted.

Buying the game usually fixes problems like these.
