There is no button in the AVRISP. In the docs somewhere it says to power the
AVRISP( the led comes on, cycles colors and settles on green I think). You
should not connect it to your target as this usually mungs communications
with the micro's in the ISP. Once the AVRISP is idle(green status led),
clock OK to program it.
This is a real pain and your lucky. In my experience, a lot of the time, the
ISP will mung code in it's secondary MCU and become dead. Atmel has an
appnote on recovering but I have yet to be successful.
This message will happen every time you update studio, a choice I think a
big mistake. The funcinality should have been left in AVRStudio and the ISP
code left frozen.
Hope this helps.

Let us know how you make out.

Where is the 'program' button on the AVRISP?
