Work saw fit to upgrade me to a new laptop, hooray! Things compile much, much faster, sweet! It has a version of Windows that isn't 10+ years old...err...yay?
My old laptop had Windows XP SP3, and I was using Studio 5 and my Dragon with no problems to program my EVK1104. My new laptop is Windows 7 Enterprise 64 Bit, which has the newest version of AVR Studio 5 (just released a few days ago, apparently?).
Before everyone sends me off to the threads that deal with installing the Jungo drivers properly, I've done that, and I can communicate with the Dragon. AVR Studio 5 recognizes the Dragon, and even can read the firmware version off the Dragon (using AVR Tools Firmware Upgrade), the problem is strictly when I try to interface with a MCU attached via JTAG (specifically, my EVK1104). See attached image for the specific error message.
I've tried uninstalling and reinstalling the Dragon/Jungo drivers, but this error seems to persist. If anyone has any ideas I'm open to trying them!
