I've tried IE, Chrome, FF, Opera and Sleipnir Andrew. None of them are working on this rig (win 7 64bit) .. I've tried reinstalling my browsers (both 32bit and 64 bit browsers), reinstalling java on top of old versions, completely removing java and doing fresh installs of both old and new versions including 32bit java and 64 bit (not even sure if there is a difference but I tried both regardless), clearing the cache in Java a million times - I've done practically everything short of reinstalling windows afaik. Live timing works on this computer now Andrew - It's just 2D that won't load. All I get is the same as the picture above. I'm not sure if that helps or not. I just did a race on a junior account though with live timing and that worked fine.
My old rig however (win XP 32bit) updated the Java fine, and 2D currently works on there.
My connection is also fine. Not great by any means but good enough.
