im still having issues with my playcenter and im not sure what sound card is in this e-machine.
You don't need a soundcard to transfer the JB3 files. You should need only one driver and one application on your PC to transfer files to/from the JB3. This still comes up frequently enough, Nomadness may or may not host them any longer, and the Creative site doesn't make it easy to get to the files, so I've added them to TS Reference:
TS Reference | Software | JB3Uninstall any JB3-related software you've installed, and re-install just the proper driver and NOMAD Explorer.
On a separate, unrelated note, sounds like from your follow-up note you need to re-install your soundcard drivers.
I've also updated the JB3 FAQ to list the above driver / application location.
