I got the error before flashing the new BH 3.1.0 and that is why i did not keep the channels. I tried to back up the channels through the OWIF bouguet editor as you have suggested and i got the error.. Then i flashed the new image...
Actually i am helping a friend who has the box. I have knowledge of linux administration and this is how i treat the box. I have never seen it, i do not have it in my hands. I am simply accessing it by CLI and try to make the VPN operate... We have guessed that the previous verion of OpenVPN was the problem, but now that we have flashed the new image and got openvpn 2.3.6 we are facing the same problem when we try to connect to an iptv provider.... Moreover we lost the previous sattelite channels! Never mind we will continue the effort...
Thanks for the support, anyway....
