Kindle Fire root/TWRP HELP!!

[ryanbart]

Hello, I am having issues. I cannot "launch" TWRP. I try to go into it but it just gets stuck on booting. My kindle is rooted as in it has the blue kindle fire screen and then after that just goes into the Default ROM that Amazon has. I cannot launch TWRP. If anyone can help that would be great! (I used KFU) Tried reinstalling but no luck. Maybe I should try the other recovery?
