Problems accessing Hotmail.com:
Double check which encryption bit you have for Internet Explorer. Sites like Hotmail require a 128bit encryption. If you have anything less, visit www.microsoft.com and download the newest encryption package for your version of Internet Explorer.

In Internet Explorer, go to Tools > Internet Options > Security Tab > Set the Internet security level to low > Advanced Options Tab > Check "use SSL 2.0" and "use SSL 3.0". (These are other tools of security that Hotmail.com needs. Also uncheck “Check for server certificate revocation”. Now clear cookies, temporary Internet files, and history.
Now again go to Start > Run and type in the following DLL’s to reinstall them:
REGSVR32 SOFTPUB.DLL

Make sure that you have the current Direct X downloaded as this can be the problem to the MSN messenger error. You can obtain it from here.

If you are running Windows 2000 make certain all the latest updates are installed as well as the latest Direct X. Windows 2000 does not support Universal Plug & Play but Direct X will help as it contains some UPNP code.

Ensure that the people you are connecting to have done the same steps where applicable. Then you can re-test the MSN Messenger functionality.

If you are running Windows XP make certain that you have QoS disabled. This is known to cause problems with Messenger's audio and may cause other problems.

Turning off the QoS Packet Scheduler:

To do this:

In Windows, click Start, and then click Control Panel.
Click Network and Internet Connection, and then click Network Connections.
Right click the network or Internet connections that are currently enabled, and then click Properties.
Clear the QoS Packet Scheduler check box.
Restart your computer.
Sign in to MSN Messenger and try again.

Use a program like Registry Mechanic to scan, and fix problems found in your Registry. Once completed, go to your Control Panel > Add/Remove and "Repair" MSN Messenger.

1) Start > Run > Type REGEDIT and press [enter] > On the left hand panel, navigate to HKEY_CRRENT_USER -> Software -> Microsoft -> MSNMessenger
