I recently switched from Windows Live Messenger back to MSN Messenger 7.5.. but now all of my chat logs cannot be decrypted since I've changed from Plus Live back to Plus 3, even though I know the password and everything.

Is there anyway of decrypting them (or at least just make them viewable again) without having to reinstall Live and Plus Live? Either through the Plus 3 preferences or maybe an external chat log viewer?

It'd be quite annoying if I uninstall 7.5, install Live, decrypt the logs, uninstall live and reinstall 7.5 just so I can view them, but if it's the only solution I guess it'll have to do.

Thanks

You'll have to reinstall Plus! Live to decrypt your logs. You dont need to uninstall anything though and to decrypt the logs, you can use the command line arguments of "Log Viewer.exe".
