Is There Any Problem With MBT Mt4 Demo server???

I have downloaded MBT Tradings Metatrader demo server but its not showing me user name and passward and also not logging in? Is there any problem today in demo account of MBT? I have tried 3/4 times today but no response?
Anyone else experienced with this problem today?
Thanks...

MB NAV demo is working fine ...

No Im talking about MBT Metatraders demo... after downloading its demo its not showing me the demo's username and Passward... Thats the problem...

I know u mean mt4 , did u try file > login ?

Yes but file and login is useless ...coz its not showing me demo username and passward ... see the screenshot and if i press cancel button than again it requires username and passward... And im having this problem since from morning

looks like their server is down. Just tried to log into it myself with no success.

Yea there was a problem with thier server today since from morning thats why demo was not working and now after downloading their demo... see the screenshot with gaps in all the pairs...
