Multiplayer "join" button does nothing

Hello all,

Recently I have not been able to play any multiplayer games due to the fact that the "Join" button in the multiplayer menu does nothing. I have tried many servers and tried both the open beta and release branches. This problem occurred all of a sudden so to my mind that would rule out any firewall issues but I don't think thats the problem.

Im running Windows 8.1 64bit and have a Samsung 970 Evo SSD that DCS is installed on.

Thanks for any help in advance.
