Following yesterdays release of Windows Live Messenger Build 1202, we've seen a huge increase of users not being able to log-in to their messenger.

If you have downloaded the individual installer, you must install the other critical portions of the Windows Live Essentials Beta in order to run the build smoothly. The essentials suite downloads Windows Live Communications Platform, Microsoft Application Error Reporting, and Microsoft Visual Studio Runtime. The links for these applications can be found below, special thanks to Jonathan Kay.

We've also had reports that the anti-virus program AVG has been causing problems letting users log-in. If your unable to login, make sure you check your firewall settings, and if you're using AVG try disabling it.

If you still cannot log-in to your messenger, please post a thread in our support forum and we'll help you fix it.
