I use Windows Live Messenger ( also known as MSN Live Messenger ) often for instant messaging. The other day I got the “80072efd” error.

Luckily, I found a few things you need to check to get MSN Live Messenger working again:

• Make sure your firewall does not block MSN Messenger
• Make sure your Windows is updated

If you checked the above things, this is a method you can try to solve the problem:

1. Go to Start, and click on “Run”.
2. Type cmd and press enter.
3. A black screen with white letters will open. Typ in the following: ipconfig /flushdns
4. Press enter
5. Type exit and press enter
6. Try if Windows Live / MSN Messenger works now

If the above method does still not solve the problem, this is a last method that might solve the problem:

1. Go to Start, Run
2. Type in the following and press enter:
3. REGSVR32 softpub.dll initpki.dll wintrust.dll
4. Click OK
5. Try if Windows Live / MSN Messenger works now

If Windows Live Messenger still will not work, then there is another thing you can try:

1. Start Internet Explorer
2. Go to the Tools menu. Click on Internet Options
3. Click on the connection tab and click on LAN settings
4. Uncheck / clear the the “Automatically detect settings” box
5. Click on OK, and then again on OK.
6. Try if Windows Live / MSN Messenger works now

I hope this will help anyone with the problem!
