I'm reporting 'Failure' each time I press space space I.
I've done this repeatedly, so it's not that I'm doing it too slow.
I need to undo everything I put on and then start fresh. I'm willing to do this without any complaint whatsoever.
If someone will just walk me through the undo process so that I can start anew, please.
To the best of my knowledge, I have this on my Kindle DX-G:
1) Jailbreak
2) Launcher
3) this zip: kindlepdfviewer-v2013.1
Thanks to one and all!

ADDED: By the way, I noticed yesterday when I did all this, that the zip contains Kindlepdfviewer, kite, as well as launchpad. Should that be correct? It's this zip that will not open, from which the 'failure' is reporting.
