Hi, I seem to be having trouble loading and launching my mt4 platform. I know it's my computer because it will load on my stepsons computer. I have tried three different reputable brokers. FXCM, Oanda, and Forex. I get the initial user agreement and start up. It then pulls up the MQL5 community website and asks me to log in. I minimize that and launch mt4. It flashes briefly as a white screen with metatrader in the blue bar. Then disappears, Then nothing. I tried uninstalling and reinstalling and logging on to mql5 and trying.Nothing on all three brokers.
