WARNING! (My account was deactivated!)
Do not use more than one tab/window/computer to run more than one video!
I was playing around last week and found you can (meaning, it will allow you to) usually run ayce and discovery tv at the same time. I checked the Do's and Dont's page and their was nothing about videos, so I figured if it let me do it, it was fine. Wrong! Anyway, I'm guessing that's what the problem is. Yesterday evening, it kicked me out and when I tried to light in, it simply said my account was deactivated. No email, no warning, nothing. I sent their support a message and hope I can get my account back.
I just know I've heard some of you mention running it on home and work computers, and I would stop.
