historical data download not working

[8h88]

hello guys,

i'm trying to get historical data on index to do a backtest of an EA.

The historical data center doesn't work. 

It's not importing data, it's not downloading anything. 

I have tick data from dukascopy but the import doesn't work. 

I tried 2 different mt4, 2 different brokers and i have the same problems.

My modeling quality is only 30% now.

thanks a lot !
