p.s. I HAVE THE EXACT SAME PROBLEM,, NO PLUGINS OR WHAT SO EVER!!!
MY MSN won't open UNLESS Msgplus.exe is DISABLED / CLOSED,,
I removed Messenger plus TOTALLY from the computer (files and registr) and re installed it ,, and problem still persists!
by the way this issue :
happened in this version of plus and previous one,,
I can send system information
does .net frame work affects messenger plus?
I use the latest of both Messenger and plus!
I am currently not using messenger plus now
I will try in that for the 15th titme now till i get a clue,, any help?
