Toutes ces rщponses montrent р l'щvidence le peu d'effort que vous faites pour faire vous-mъme l'analyse du problшme qui se prщsente р vous, mais aussi notre bonne volontщ р vous щcouter et vous aider et finalement notre lassitude р rщpщter qu'on y est pour rien et qu'on aimerait vous aider р des recherches plus nobles.
Hania, donne-vous exactement le numщro de ta camщra logitech et le nom et la version du programme informatique ayant gщnщrщ ce fichier.
