Thank you for your kind reply. I've checked those two things you've told me.
I made sure that everything is up to date, to the version of 0.1.7a, but the message still pops up.
One of my friend is experiencing exact same issue as well. Sorry for making trouble but it'd be great to have a 'bypass' button. It's too bad that I cannot enjoy your game yet, but thank you for the game though.
