Unhappy [Q] KINDLE FIRE 1st Gen: Accidentallly wiped original rom and can't install CM

Today I rooted my original Kindle Fire, having great plans to install CM on it and get rid of Fire OS. I downloaded CM to my Kindle Fire from the web, booted into TWRP and wiped everything except the SD card with CM. I then tried to install the CM zip and received an error message. I cannot boot into any ROM!!

Please help!!
