The main issue I am having after running the .azw2 file is "The title is not signed by a registered developer"

I have signed with dn,di,dk with the following line:
jarsigner -keystore developer.keystore -storepass password Test.azw2 dktest

And also tried with Test.jar with no avail.
I have tried using the developer.keystore from this forum and also tried just using the mkk install file.

I am at a loss of what else to try, have you guys got any suggestions?
The message indicates that either you have not signed the package with one of our keys or you haven't installed our keys (for your device, re-install the 'hotfix' package (any of them) which includes installing the keys).

Note:
If running 5.9.anything on a PW3, then "Active Content" is no longer supported and even once you figure out the signing problem, it is not going to work (but you will get a different error message).
