I bought a generic Battery grip for my Canon 60D of ebay after seeing many posts from members of this site saying that there's were fine and that their was minuscule difference between the generic and official ones. Mine came on Wednesday and until now had been working fine. Now it causes an error in my camera. As i take successive photos or even try to turn video mode on it crashes. What exactly happens is that the light on the right hand side goes a constant red, then the top screen says: "Busy" then "err" starts to flash on the top screen. The error remains after turning the camera of and only returns to normal after taking the batteries in and out of the grip, but as soon as you try to use the camera again the problem returns.

The camera works fine however with out the grip, so it's obviously the grip's fault. If it matters I tried with multiple SD cards including a class 10 one.

anyone have similar problems? googling it provided no answers.
would really love to fix it rather then sending back as it was from Hong Kong and apparently I have to pay for the return shipping.
