Hello guys, I've been using msn messenger on a windows pc, but as soon as i switched to using my mac, I noticed that all my contacts on my msn list have been blocked and no matter what I do, I cannot get them to unblock. I have googled my situation and it seems that many other users are facing the same problem, but none of the solutions that I have read solved my problem. I am very frustrated and this happens on any messenger, even on a pc. Can anyone help me out here? Thanks!
