connection error & unable to retrieve Market Data

Hi there i have installed S#.designer but i cant seem to make it work. it doesn't acquire market data and every time i press start button (after selecting preferred securities) it get stuck on "Loading Data. Wait" forever, plus i get lost of connection error (Studio Connection or something like that) all the time. my next question is that is it possible to connect S#. Designer to other brokers such as FXTM?

Thank you in advance
