METATRADER 4 and WINDOWS 10

[Mario Trinchero]

Hi,
I have installed on my PC WINDOWS 10 and METATRADER 4 works well.
I just had to login again on all my metatrader accounts because all passwords are deleted.
Unfortunately, every week there is a new released, and every released i lost all passwords of my accounts!
Does anyone know the cause?
Thanks to everyone in advance
