And i have two msn messenger, one is Personal contact and the other is Corporate contacts..How did this happen ? I have not chatted on others computers so I wonder why is this happening. It's a pain because I don't get the Notifications everytime I have new emails. My main account is hotmail .Can anyone help me out ?
