Notice the revision number in the archive name of the archive taken from the snapshot thread?
That is significant.
But your post did not include enough of the archive name to tell the difference between the two.

Be very certain to use the proper Update_*.bin file from the snapshot archive, the one with the revision number in its name.
It will not do any harm if it (or an older one) has been installed.

Then explain (while trying the most recent, proper file) what you mean by "does not work".

Thanks again for the reply!
I'm re-doing pretty much everything:

1. Restore Default settings
2. Jailbreak with kindle-k4-jailbreak-1.8.N
3. Install Update_mkk-20141129-k4-ALL_install.bin from kindle-mkk-20141129-r13408.tar.xz
4. Copy KUAL-KDK-1.0.awz2 into /root/documents folder, from KUAL-v2.7.zip
5. Still getting the same errors: An error occurred: Main Class Instantiation threw a RuntimeException. Please contact the developer.

Am I suppose to copy some other files or folders from Kual-v2.7.zip into the /root or /root/documents of my K4?

Edit, this is the crash.log:
