Ok ... so !
After 10129823 errors I figured out that in the same area, killing the same type of creatures my friend got the same error ! I went to another area ... started killing other creatures ... I played for 5-6 hours ... no problem.
I went back, tried to kill a Bloodscalp Witchdoctor and BANG ! ... Error #132
Anyway ... I'm glad I figured it out ... in a way ... and now I can play the game !!!
