Kingston Hyperx firmware update failure

Hi there. I bought a Kingston HYPERX 120GB SSD drive recently. All worked fine, until I tried to update its firmware. Once I pressed the button for the firmware update, my PC hung. I waited for some 15 minutes, but nothing changed. I tried pressing Ctrl+Alt+Delete but nothing. Not even the mouse pointer would work. So I pressed the restart button. Now the disk is unrecognizable in BIOS. I tried booting my old installation of Windows 7, and run the update program. It does not recognize any drive either. So, any ideas other than contacting Kingston? Thank you in advance
