Hey everyone, I've been having problems signing in to MSN Messenger (Mac version) since late this afternoon. I have no idea what's causing this... nor do I know how to fix it. Earlier this morning, I had no problem signing in, but now I just can't. I know it's not my internet connection. I tried re-installing the program but it's hopeless. Has this happened to anyone? Does anyone know how I could fix this? Thanks in advance!
