To make sure everything is back to default, do a clean install of both MSNM and plus!:
- Uninstall MSNM and Plus! including preferences and plugins (plus! uninstaller will ask you that when uninstalling)
- Reboot
- Remove all folders in program files folder pointing towards MSN messenger and Plus, also delete C:\Documents and Settings\<username>\Application Data\Microsoft\MSN Messenger
- Reinstall MSNM and Plus! (download them both fresh preferably)
With this method you will loose everything ever set in/with MSNM (including custom emotes, backgrounds etc.), Plus! and plugins.
If you wish you can make backups of:
- Plus! Preferences: plus > preferences ... save/load at the bottom
- Plus! custom sounds: open soundlibrary > add > export to soundpack
- CE/DP/Backgrounds:
CE/DP Backup Wizard. Doesn't say it works with MSNM 7, but it does. You can place those emotes etc. back one by one (manually) or with a CE/DP manager, wich you can find on

If you do decide to make backups of these, please check if everything is still working fine after each single thing you put back.
