Impossible to finish a game now

Hello
now, that you are limited to 1 game per day without pro (which is a little joke, but ok), it's impossible to finish a game.. I can't even refresh with f5 to get rid of the black screen, which occurs every 2nd location..
I really had a fun time, but now I can't play a single game..

how can I delete my account? I don't find the option...
Thanks
