Problem with n364 keyboard.

[cirE]

Hello I joined this forum to ask a question because my sisters keyboard is not working what I did is I bought cakewalk sonar 6 and it worked but then it wouldn't work when I unplugged it from the computer it did'nt work so then I tried it plugged back into the computer and it does nothing there either I would really like to get it working again. what should I do?
I don't know where to post this b/c there is no forum for n364s.
