1. Try these 4 Microsoft HotFix... Microsoft has released 4 Microsoft HotFixes. These 4 Hotfix which I can neither verify or discount. It may work, it may not. (One is required after installing SP1 which is below how to install SP1.)
2. Upgrade to SP1 and this HotFix SP1 provides bug fixes, improvements, new features, enhancements and much more. If you wish to upgrade to SP1, use Windows Update or use Microsoft Download Center if you are installing SP1 on more then one computer
