another log in

I was playing then a message came- another log in detected, I could not play anymore and so I lost a couple of times.  However I did not log in again. What is wrong?

I suggest u to verify security of your account and maybe changing your password.

Damn. I had the same message a couple of times. Does it really mean somebody hacked my account?

I do not know,but if u change password u r safer i think.

Thnx , I will change my password.

That happens when there is a session to Live open in another background tab or on another device. Some devices/browsers will refresh background tabs and can cause an idle session to become active again, which will cause that message/problem.

Martin, 3 times in a row?

Depends on the your device usage patterns and refresh rates. I'm not going to say it couldn't be something else, but most of the time, it is that. I've had it happen when logged on to the website and I open my app for something (which automatically launches a Live session). I've also had it happen once when I left a tab to Live open on another computer.
