Hi Uden,

To fix the problem follow the next instructions carefully.

Before doing so, please read  Microsoft’s Registry Disclaimer:

“If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.”

You can take a back up of your Registry before you make any changes, so that you can undo the changes if you go wrong.

Click on the Start button then click on Run. On the Run box, please type REGEDIT and click OK. This should open the Registry Editor window. then click on FILE at the top left corner of the registry window and select EXPORT and save it on your Desktop.

Now you can follow the instructions listed below.

Double click on Computer then double click on HKEY_CURRENT_USER
Double click on Software, Click (>) beside Microsoft
Click (>) beside MSNMessenger
Delete PerPassportSettings
Close the Registry Editor and restart your computer.

If in case you this doesn't resolve the problem try Uninstalling the Windows Live Essentials from Control Panel and reinstalling it.
