My old msn had tons of viruses so I made a new one, I imported all of my contacts from my old msn to my new msn but there is a couple of contacts that it wont let me re-add. They still appear on my old msn but not on my new msn and went I asked them about it they said they hadn't recieved an invite asking to be added to my list and even when they tried adding me it didn't work
