I'm having a really confusing time right now.
I've never had any problems with the loader, in fact I've been using it for my Teensy++ 2.0 for months. I plugged in the 2.0's I bought a week ago and now the loader doesn't work for either. Below is a video with this behavior. http://www.youtube.com/watch?v=TeqohEXw2_o&feature=youtu.be
The IDE compiles for the Teensy 2.0, but I have to rummage through my temp folder to find the compiled hex manually with the loader.
To try and make sure it wasn't just the Arduino install, I now have 1.03, 1.53, and 1.02 (my original install) and I've installed the Teensyduino package on all of them.
Any ideas would be greatly appreciated.
