Hello Anthony,

Thank you for contacting MSN Messenger Technical Support. My name is Dave, and I will be happy to help you with this issue.

I know that this situation can be very frustrating not to mention disappointing on your part. With this in mind I would like to assure you that I will do my best to try to resolve the problem that you are experiencing.

According to your email, after the computer rebooted Windows Live Messenger did not show your sign in details.
I understand when you type your credentials (email address and password) there is a delay and, the sign in process fails with the error code 800401f3.

Below, I have included the steps to try to resolve this issue, but before you do it, please be advised that we specialize in supporting the MSN Messenger product version 7.5 and below. Therefore, if you encounter any additional problems after having gone through the steps, I would suggest that you contact Windows Live Messenger technical support at:

The following reasons may be causing your issue:
- The MSXML library files are not registered.
- The MSXML library files are inaccessible.

To help resolve this issue, please follow these steps in the order they appear:

1. Reregister the Msxml3.dll file:
a. Click "Start," click "Run," type the following command, and then click "OK:"
Regsvr32 %windir%\system32\msxml3.dll
b. If you can locate the file and the file is available, you receive the following message:
"DllRegisterServer succeeded in C:\Windows\System32\msxml3.dll is succeeded."
If this step is not successful, and you receive the error message that states that file cannot be found go to step

2. If you receive any other error message, write back to us so that we can follow up with other troubleshooting steps.
If this step succeeds, go to step 3.

a. Visit the following Microsoft Web site:
