I've got a microsoft surface running Windows 8.1 and can't get the race control to connect (just see a black blank screen). It occurs in IE and Chrome, i've turned off the firewall, installed Java 7 u 71, made sure i've enabled NPAPI. I've clear the browser data. Any other ideas i can try in order to get the race control to work? Thanks.
Java7u71? That's outdated. Maybe that is the reason the browsers reject running java applets.
Get latest Java8 and try https://java.com/de/download/installed8.jsp?detect=jre to verify java applets are able to run.
Hope that helps.
