Firmware update problem

Hello guys. I installed my WD My Book at my new pc. I have a WDBAAF0010HBK model. All things were good until i did the stupid thing to update the firmware. I downloaded the firmware updater from here, i run it and it said that my firmware is ok and i don’t need update. But i wrongly clicked the update button and it started to update. At some point the update failed and My Book turned off the lights that show you the capacity of the drive and the only light that was on was the small one under the locker. I restarted the pc but nothing. My Book now is not visible at Windows 8(i search with Disk manager and with a program), it doesn’t turn off if you unplug the USB cable from pc and i am afraid that i lost all my data. It seems like it is stuck. Can you please give me some advice?Thank you in advance and greetings from Greece.
