Hi
I have purchased a Skystar HD 2 recently . The driver works fine in windows XP but it doesn't works with windows 7.
when I install the driver it shows me the technisat Skysatar HD2 installed properly but when I run Progdvb 6.51.6 it doesn't recognize my Technisat Skystar HD2!!
it says "BDA Mantis device not start" or somthing like that...
what should I do to solve this problem?
