Have you searched for this problem online? or tried a different computer? I know you all have friends and I am sure one of them has windows xp still on a computer. Also I remember getting something like this once, but I searched on google and found a solution or two. Good luck, and I am sorry that you havent gotten anything back yet.
Also dont worry about the lawyer, I am sure that Bill and Corey will be happy to refund your money, from what I have seen they are good at that, but dont take that as a promise, I just have seen that type of service in the past. Keep trying to call during business hours, or try their facebook page, or send an email, or E: all of the above.
Hope I gave some ideas on how to fix the problem. And i still am sorry that it hasnt been worked out yet
