Exactly, what was your workflow for installing DSON and the starter bundle?  There really shouldn't be major issues if all components are installed correctly, and that includes Poser.  If Vista, Win 7 or Win 8 is your OS, Poser should be installed by it's default settings, the main program in either program files (64-bits) or program files (x86) (32-bits) and it's content loaded into a different location away from the program files folder.  DSON, either 64-bits or 32-bits, must be loaded into your main Poser runtime.  No where else.  If for some reason you installed Poser Pro versions under both 32- and 64-bit program file folders in 64-bit OS, then you will need to install both DSON versions!!  At this point I would uninstall and reinstall Poser properly.  The Genesis Starter bundle, both DS core and Poser companion files should be installed into separate external runtimes, perhaps in the same location where the Poser Content resides, and link both to the Poser Library.
