You keep getting error code 80048103 when you try to sign in to Messenger? This might be caused by your nVidia firewall.
- Thus, open your Control Panel, and look for the place where to uninstall programs.
- In the list, find “Nvidia Network Access Manager” and uninstall it.
- Reboot your computer and retry to sign in to Windows Live Messenger.
Be sure that you still have a firewall. You can simply use Windows Firewall, located in the Control Panel as well.
