Can't find external hard drive after aTV Flash 3.5?

I was wondering if you guys could help me out. I had the previous version of aTV Flash and it worked flawlessly, I was able to load all my movies from my external hard drive. After installing version 3.5, the hard drive is no longer there. I have tried unplugging and plugging back on both the hard drive and the Apple TV. I have tried reinstalled aTV Flash and still nothing.
Am I doing something wrong?

Did you happen to run the Smart Installer after installing aTV Flash 3.5? If not then check out:
