How did you manage to have that???
Normally to uninstall module , you have in the Atomic folder one .exe by module which is named : Pnp_<module>_uninstaller.exe , if you run it it will uninstall the module.
If after you have uninstalled the module it still appear in PnpManager , go in the folder <atomicfe>\plugnplay\ and remove the file pinball.pnp .
