Hi Martin and Christian,
I wanted to thank you for your helps so far, even if we didn't found where the problem came from.
I'll be off my studio untill mai 12th and my demo version will come to and end so I don't know what to think know...
VE3 seem to be a good solution and 'ill be ok to spend the 95 euros for the definitive authorisation but i'll be in a much better
situation if i knew this is working fine on my system or knowing what's wrong in my system to make it work properly.
If you have further ideas please let me know and i'll check that when i'll come back.
regards
stephane
