Just got word from our good friends at Neowin that they now have a fix for MSN Messenger 5.0 Build 317 Beta. Here's what they're saying:

As you all know there is a leaked version of MSN Messenger v5.0.0137, though it's still unusable because you can't login, this is now fixed. There was also the problem that you couldn't stay signed in longer then 30 seconds, also this is fixed. Download: Messenger 5.0 Build 317 Beta FIX
