[Q] I can't seem to switch from Kindle default launcher to anything else?

view story

http://forum.xda-developers.com – I just bought a Kindle Fire HD for my husband. I have rooted it and would like to change launchers. I HATE the carousel! I've sideloaded and installed Go Launcher ex and ADW Launcher Ex but neither seem to be permanent. Go launcher crashes and ADW is fine EXCEPT when touching the Home button then it reverts back to the kindle launcher. I REALLY don't like the Kindle home screen and would like a permanent fix. Any ideas and help would be appreciated (HowTos)
