I have read @ other forums that some people are up again by just rebooting,even though I reboot stb from rear every day and to no avail,I also read that its a sever addressing issue which means they need new bin to fix the recurring problem.
The ones that use the Japan server (Sonicview, Limesat I think). You can use the Viewsat's too and other receivers that support private servers all you need is the X-FTA router. You can get one on eBay for $70. Then just set it up for the Japan server (I think it's $50/year?). It does support the Viewsat Ultra and MaxHD, etc. It supports or brands too, but not sure which.
