hello about MT3

 
hello

when i download MT3 and want to register,when i registered and clic to open it for the first time,there is a message saying
can t connect, you must open the port 1950
i got an adsl modem
and at the time ,it was working great.
please how can i do to do it?

regards
 
Most probably, your broker move demo-accounts registration on MetaTrader 4 Server and on MetaTrader 3 Server you cannot open new demo-account, because new demo-accounts registrations on MetaTrader 3 Server are disabled.
 
yup but i downloaded the free demo account in here .
that s right i took a demo account on one broker ,but mt3 is free if i download it in here
please how to resolve it??

thanks
