NIS - Norton Internet Security
I suggest you reinstall/repair MSN 7 aswell.
Also check if you have one of these things
(if MSNM won't connect with Plus! but will without Plus!):
- Handwriting plugin - not needed anymore in MSNM 7 (built in), remove handwriting.dll from plugins folder
(C:\Program Files\MessengerPlus! 3\Plugins)
- SPNG 2.2.44 - update to latest version,

- Smileycentral, if you use that here are the
uninstall intructions.
