Based on the lack of you saying you own the box, which if you did, you would be able to troubleshoot aircrack-ng from there. I suggest you read the following. Pay attention to the parts that deal with breaking the law perhaps, and then read the rules of the forum before posting again please. I just picked a random law, there are many many others you should be very well aware of man....
US Code, Title 18, Part I, Chapter 47, Section 1030 - Fraud and related activity in connection with computers
