lol, it even signed me out the first time I tried to do this and of course I didn't copy text so have to do all over again.
I have a 1 1/2 year old Dell with Windows 10 and use the browser (Explorer? I don't know) it came with. The game signs me out every few clicks and in an odd quirk, it always takes two attempts to sign in.
One other clue may be that every time I want to watch a game live it tells me I don't have adobe and I click on the screen to get a one time use of adobe. Is the lack of adobe causing the game to sign me out. I don't have this problem with any other of my websites.
