As the title says, when I click on a multiplayer game it will not let me join and not even the join game button works. Trying to make a game either doesn't work when clicked or leaves a blank screen.
Upload your DxDiag.txt, so we can take a look at your system configuration and figure out what's causing issues from you. Instructions stolen from SXX: There is also this bug report though: FS#4049.
I had a similar experience last night. Admittedly I was running a butt-ton of mods so not really enough to verify anything. I found that spamming left click *hard* on the 'join game' button eventually led to a successful join attempt.
