Bumping this up.
For those who know hacking, you can download the software at
http://media.naturalpoint.com/softwa...IR_4.0.021.exe
http://www.naturalpoint.com/trackir/...downloads.html
For activating it asks for
Vector Serial
Vector Hash
TrackIR serial (filled in if you have a trackir)
e-mail address
first name
last name
I'm guessing that it sends the info to natural point.
