My Box not working..

[ransiri]

sometime this is not a correct section to post this. But i couldn't find the right place to post this and this is urgent...
A day ago when i download .dll came message "connection error/ gracefully closed server" and automatically close my interface.
Since that time when I open interface cannot connect "update server"
Just I can see "connecting to the update server...../"...

What I do...? I wanna immediate reply
