I downloaded PDANet software on the Droid and my laptop. Both my laptop and Droid went blank and would not start back up. I had to resolve the issue by removing the batteries in the laptop and also my Droid and putting them back in to get them both to start back up. I have not tried to tether since. I have the 2.2 version on the Droid now. Any thoughts on why this happened? Should I just retry and hope for the best?
