Windows Live Messenger will display this error for a number of reasons some of which include incorrect Internet Explorer settings, registry DLL files, firewall settings, or a malware infection. If you have checked for a virus or malware, and your firewall is not blocking Windows Messenger there are a few other troubleshooting steps you can try.
To double check your settings in Internet Explorer click on Tools
in Internet Explorer and then choose Internet Options
from the drop down menu. Choose Contents
and then click on Clear SSL State
under Certificates and then choose OK
. Click on Advanced
and then choose Restore Default
. Change the screen to Connections
and then choose Local Area Network Settings
and remove the check marks from all of the boxes next to this setting. Close the window and try to sign in to Windows Messenger.
If you are still experiencing problems it may be necessary to re-register DLL files in your PC’s registry. You can do this by clicking on Start
on your main toolbar and then choosing Run
from the menu. When the Command Prompt appears enter regsvr32 softpub.dll
and then press the Enter
key. You will need to repeat this process for the following files as well and press the Enter
key after you enter each file in the Command Prompt: regsvr32 Cryptdlg.dll regsvr32 Dssenh.dll regsvr32 Gpkcsp.dll regsvr32 initpki.dll regsvr32 Mssip32.dll regsvr32 Rsaenh.dll regsvr32 Slbcsp.dll regsvr32 Sccbase.dll regsvr32 wintrust.dll
These steps will re-register the necessary .dll files for Windows Messenger. When you are finished try signing in to Windows Messenger again.
