Flash can still crash without updating. It might require un-installing and then re-installing the same version of flash (if that's what is best for your browser) to fix it.
I have 2 browsers i use for WGT. Maxthon Cloud, my main choice, and Opera, as a back up. Last night I ran into a problem on Cloud where it would bump me back to the Lobby without warning while trying to start an 2 player MP game.
I changed to Opera and had no further problems. You might try playing a round or a free Tournament on another browser and see what happens. Just something to consider.
Good Luck and I hope you figure out whats going on.
