dj air not working even after trying all suggestions found in this forum..

Question

hi all,so ive had my dj control air for about 8 months and everythings been fine... until about 3 weeks ago. heres what went down:before the air went dead, i reformatted my pc to windows 7 64 bit (could be the problem?) and i proceeded with downloading the updated drivers from the hercules website for the air and followed all installation instructions down to the line. this didnt work the first time, so i tried uninstalling and reinstalling and still did not work.i then tried changing usb ports and went through the same process again, still no luck.i noticed by this point that whenever the installation process prompts me to plug in the device, the airs buttons and lights do not light up. and if i remember correctly, they should light up just by plugging it into a usb port..after exhausting all usb ports on my cpu, i tried installing the air using a mac first. again went through mac installation procedures down the line but still failed.i then tried installing the air with a windows laptop this time, and still no go.ive also combed through a great number of topics on this great forum regarding troubleshooting and what not, and still i havent found the solution.now assuming (with all the forces in the world hoping that this isnt the problem) i do have a dead unit, will i be able to still ask for a replacement unit even when im in southeast asia? ..i know its a longshot but i really enjoy using this controller...i hope someone can help, any info needed im willing to provide still.thanks.
