Invalid account message

 
Suddenly today I cannot connect and the status bar shows "Invalid account". Does anybody else have the same problem?
 
I have the same problem and I can not create a new valid account.
 
Ask question your broker
 
hi Slawa,
it is the demo account downloaded off your site. There is no broker, as far as I know.
 
I cannot answer your question because You do not tell account number.
 
The account has come back live again, but the 1 min GBPUSD chart shows a gap in the data between 09:51 and 09:57. The server I log on to is MetaQuotes-Demo. The interruption to the log-in facility was longer, and I noticed it when I made my first post, about 2 hours ago.
 
thankyou Slawa
