Dreamkey 3.0 backup resets Dreamcast

[konio38]

So guys i have downloaded two diferent versions of dreamkey 3.0 from two diferent scenes on both i have the same problem, the Dreamkey boots fine and i get to the Main menu there when i press "Start" and then "configure" my DC goes into a black screen and resets sometimes doesnt even resets just gives me a black screen. I would like to know if any members also had this problem, i dont know if its a bad burn or bad dump. Anyone has any ideia of what i could be?
