About a week ago I noticed my contacts names were the same as about a month ago, some just had their e-mail address and some were fine. I'm not sure why they aren't changing back to the name they have now because they have since logged in and had different names, but it still shows their old ones.. I've had WLM for months now and it's been working fine, so I don't know why this has happened.
I hope this makes sense and someone can help, thanks!
