I post my problem also in a italian wd support without result.
Do u have an idea how can resolve this problem?
I have windows 7 and the last versione of Java.
Thank u very much.
Try to disable any firewall that you might have active, also see if you have all of the available windows updates installed.
Thank u so much but problem isn’t fix.
I’m sure that is a problem of my notebook with windows 7 because I try to open folders on other netbook with windows XP and here do very well.
Do u have other kind of solution? I’ve one… destroy my notebook! 
Thx
