It's done, thanks to supernoro!
After Experimental a few times I have found out that the trigger for the Problem was the Components Section. If I write anything in there the Internal Compression will not work.
I hope the Installer works without an Components entry Problemless. Will Report back if everything is fine, still Compressing.
==EDIT==
Everything works now! So for People who might have the same Problem
Don't make an Entry in Resources/Components Section!
And Razor, The transitions in the slideshow are Animated, can I or you Change it somehow? I hate it, looks crappy.
