question about MSN Messenger and IE

[ventrox]

i'm not sure if it's here where i should post this

but i have a question, if i posted in the wrong forum, feel free to move it

the thing is, when i'm on msn, i want to go to my inbox, and whenever it opens, it gives me this page (see attached picture)

it tells me that the username/password is incorrect

but i'm logging directly from MSN Messenger

i don't know why, it wasn't like this, and don't want it to be like that

is it possible to fix it?

i'm using IE 7 and Live Messenger 8.1

thanks
