Now for the past week or so, I've been having some problems with Mac:Messenger. I can sign into the application fine. However, it signs me in, but displays all my contacts and myself as offline. After abut 30 seconds after being signed in, the program signs me out. This is really frustrating. I've completely removed the application from my MacBook and re-downloaded it, however it still gives me the same problems. This is how it appears after I sign in: Any help? Anyone else experiencing this issue?
