The same thing has happened to me on multiple occasions, where something goes wrong while you are in the middle of a tournament/round, which requires you to shutdown the browser. Then when you start the browser up again, if a WGT advertisement (such as "Hole in One Challenges") appears, then you do not get the option to continue the tournament.
I found if you shutdown the browser again and restart it, you may not get the WGT advertisement, which then will allow you to continue the tournament. Once I had to restart my browser twice before the WGT advertisement did not appear, which then allowed me to access the continue tournament screen.
I use Comodo Dragon browser, don't know if that is a needed condition for this bug to occur.
I've reported this bug a few times with "Submit this problem to WGT" and in some other thread in this forum.
