Uplink issues

[idiotplaysgames]

It appears as though, even though I was on yesterday, I am now unable to uplink and join a server (even singleplayer) and gives me the error "SSLHandshakeException: sun.security.validator" any ideas???

I am getting this too. Just hours after playing without a problem. I never had to uplink to play Sandbox, but now it's saying it is required.

Just redownloading the game works @Invader
