Last night my STK500 suddenly stopped being able to program any uC I tried. Attached is the screenshot of the error I get from AVR Studio. I'm not really sure what to even look at, I haven't changed anything. The ISP6PIN cable is connected to the red stk3000D3 port. I've tried several different ATMega16's and an ATTiny2313 as well, all with the same results. Any ideas?
