Problem with MSN Messenger installation

well, I have been always updating my MSN messenger when ever a new realese was available. and with the new "Windows Messenger live Beta" I was having serious problem. Every time I logged in, after 3-4 minutes it gave me an error message and quit. I decided to uninstall it and move back to the original official release of MSN messenger. so, I first uninstall the Windows Messenger Live beta. Then I tried to install the offical release of msn messenger but a window popped up telling me a newer verious is already present in my pc and I have to unistall the newer version. so i checked my add remove program lists and saw msn messenger beta, which was the earlier verrsion before windows messenger live. so, i try to uninstall it, but it it says, necessary files were missing. so i just deleted all the msn directory from the program files folder and then, run a registry cheker and remove all invalid registry entry. but the sad thing is, still I couldn't install the offical MSN messenger. Still it is saying, the installed messenger version is the new one, and i have to uninstall it first. I am running out of tricks now. So, does anyone else have any idea, how can i get rid of all the traces of my earlier msn installation with out formating and reinstalling windows.

Any help will be greatly appriciated.

 

yup! At last I have formatted and reinstalled windows.

 

pretty drastic. if i recall, that was a bug that has been fixed.
