How connect to the Q10Pro from SAMBA in firmware 2.0.1?
"administrator/password" didn't work

From FAQ:

* Share Q5/Q10 Pro internal storage / internal HDD / USB storage on a network? Turn on Samba sharing. Go Settings - More - SAMBA Service - Start. You can add password protection if you wish. This will share the internal storage, internal HDD and all attached USB storage using a Samba (Windows) network.

Yes. I have enabled samba sharing. However when I try to connect  Q10Pro ask me username and password and the default "administrator/password" didn't work. I tried to change the password it's doesn't helped. The Q10Pro writes that the username or password isn't correct
