Invalid Account

 
Today I suddenly get "Invalid Account" message in the status bar, but I just use it last night. Anyone know why please? I heard the demo account not expire as long as you keep using it...

What if I want to purchase a real account? How much will that be and how can I do the purchasing please?
 
Demo-accounts may expire, it is the server setting. On our demo-server demo-accounts haven't expiration time. Server delete only accounts not used within 1 month.
For real account opening you should ask broker support team.
And if you'll have problem with your real account you should ask your broker support team too.
