Unhappy [Q] Help! I somehow erased all the abd files and now my computer shows no kindle

I have a kindle fire 2 that was flashed by the Kindle Fire First AIde with compete success. Then my husband got a kindle fire for Christmas, and I had to flash it again. But this time, it took me another two days because all the ADB files I tried didn't work. An worse yet, I didn't keep a copy of that file on my computer. Worse that that, I showed the hidden devices in the control manager, and erased the three kindles that were there but not working. Now I don't know if I can automatically reboot them back on my computer, or if there is some procedure I need to do.

I'm totally addicted to my kindle, and need you kind people to help me out!
