Thank you for the follow-up information. From what you're describing I would guess that the MSN Messenger install didn't install the MSN Messenger program correctly which caused the program to fail to run correctly. If it "hung", then it is likely to have caused assorted other problems.
Since the second attempt to install also failed in the same way, I would guess that the program left some elements in your system which are conflicting with the second install.
You can try removing all the .tmp files on your system (these are "temporary" files and will not harm anything if removed).
One way of removing .tmp files is to restart the computer in "Safe Mode" and then running a "Find" / Files or Folders for *.tmp files in your C:\ drive.
Restart your computer. At the first screen or the
Power
On
Self
Test (P.O.S.T.) beep, repeatedly press the F8 key. When you see the Windows Start Menu, use your arrow keys to scroll to #3, Safe Mode. When #3 is selected, press the "Enter" key.
In Safe Mode, go to Start/Find/Files or Folders and type in *.tmp in the "Named" box. Set the "Look In" box to C:\ and click the "Find Now" button.
Select whatever .tmp files are found press the "Delete" key on the keyboard.
While in Safe Mode, you may wish to run the Scan Disk and Disk Defragmenter.
Right click on the "My Computer" icon and choose "Explore". In the Windows Explorer look in left pane for your C:\ drive. Right click on it and choose "Properties". I suggest you run the Disk Cleanup tool and allow it to clean out junk files. Then click the "Tools" tab and run both the Scan Disk (Standard Mode / Automatically fix problems checked) and then the Disk Defragmenter.
If you have a screen saver set to run, you will need to set "None" while the defrag is running to prevent the defrag from having to start over constantly.
Right click on any unused portion of your Desktop and choose "Properties". In the Display Properties window, select the Screen Saver tab. In the selection box, select "None" and click on OK.
Depending on how long it has been since you last defragged your system, this may take a couple of hours or more to run. You can leave this running overnight if you wish.
Once all this is done, restart your computer. It will restart in Normal Mode. Reset your Screen Saver as desired.
If you like, you can print out this long list. There is a "Printer Friendly" tool you can use.
You can try the MSN Messenger program again.
