Hello,
According to several answers, my problem could be due to the 32 bits build.
I hope I will try to make a 64 bits build in January, in order to give
you more explanations about the possible errors I will encounter.
I keep preciously your advice, and I hope I will be able to give you an
answer in January.
Thank you.
Regards,
Alexandra DANTE
