You can try Alternate mode:
- Plus > preferences > miscellaneous..under Messenger Plus! Automatic Recovery Options, set it to "Alternate".
- Reboot
- Start MSNM and check if it's still in alternate mode
- Ctrl alt del to go to taskmanager and in processeslist end msgplus.exe
- Now restart MSNM and see if Plus! appears in the menu, if so "alternate mode" is working fine.
- After checking you can remove Plus! from startuplist by going to: start > run ..type: msconfig <enter>, go to startuplist and uncheck MsgPlus (this step isn't really needed, if need be Plus! will switch to "Allternate" by itself, just check if it's still set to "Alternate" every now and then).
Edit: you're welcome
