Admiral Markets

I opened an account with Admiral market, on the pc platform MT4 works regularly, but instead on the server tells me connection zero, the broker does not respond..What can i do?

I'm trading at Admiral Markets and I'm satisfied with them, low and fixed spread, nice customer service.

Have no problems with them either,
Recently hooked me up for a lucrative deposit bonus(Trade More-Get More). Making my volume, everything is working out good so far!
