Hi, I have just bought a Star Net NS-K4600 Super and want to patch it. From where do I get the firmware for this receiver please?

I tried to patch with file ALI_DVBS_29B_DVR_CI_031808, but when I started ALI Mini 5.1 upgrade I got an error stating that "You are running incompatible firmware. You cannot update STB with this tool.

Any help is much appreciated.
