package name

hi guys

my little game is almost ready, it´s supposed to be an update of an app i´ve build 2 years ago
this old app was build with an other software (HAC). i used the old keystore file and it works, except the package name.
as package name, i´ve choosed "de.NussMichel" in the old app, but it seems that fusion demands two dots as like "de.Nuss.Michel" for example.
but i need "de.NussMichel" else i can´t do an update akp - what can i do?

thanx in advance

thank you for your answer, but this tooo hard to understand (for a advanced newbie like me), is there no easier way like "download (tool.exe), set (my App), change package name..."X)

what about a manifest.xml file, how can i create one for the fusion made app?
i think i can change it via eclipse can´t i?

no ideas?
i´ve loaded apk editor pro on my phone.
i can change the package name, but the app don´t take the changes.
i´ve tried some solutions, but in every each of them, i have some other troubles to rename the package...
