MT4 Demo not working..

Hi,
Today evening, I see my MT4 demo platform is not connecting to the server---my demo account is still active----the system also is not able to open a new account in case that was the problem.
But, I can connect to FXCM platform (so it's not my internet connection)---
Anyone has any explanation? What should I do as I use MT4 charting servce?
TIA,
GL/GT

maybe shuit down pc and start again..i had same problem with Atc MT4 but it started working at 6...

Thanks Ansh----It worked!
