Guild Wars 2

Posting from a tablet because every time I try to log in on my computer I enter email and password and am taken to a completely empty page. No error message, just nothing. I tried waiting but it’s been a week and I still can’t log in. I know my password because I just used it to log in on the tablet, my account hasn’t been disabled, I’ve turned the computer off and on many times, etc. I can log in to Gmail and other websites no problem. I can log in to the game. It’s only this website and this computer. It is a “new” computer (hand me down), and still has tons of mystery junk installed on it..
