Hi Mattcscz -
Since the Jet Demo does not remain open, that indicates the device is either not being recognized or the driver is not being allowed to start.
More important than a clean install at this point is for the Space Pilot PRO to be recognized. Is it plugged directly into a USB port on the PC ? Have you been able to try it on another PC? Is this a personal PC where you can disconnect from the internet and temporarily turn off security/ firewall applications ?
To answer your question about profiles, the 3Dconnexion profiles are saved as .scg files.Some of the applications also store button mapping information in the registry locations listed in the clean install steps.
In Windows 7 the .scg files are in
C: --> Users --> [Username] --> AppData -->Roaming---> 3Dconnexion --> 3DxWare --> profiles
To find out which .scg file your application is using, hover over the 3Dx SystemTray icon with your standard mouse while the application has the device focus. The profile name is listed along with the .scg filename in parenthesis - i.e Maya-username(user05.scg)
In regedit you can use Export to save entries to a .reg file before deleting them. Once you have completed the clean install and have verified that your Space Pilot PRO buttons are working correctly , you can right-click on the .reg file and use Merge to restore it.
If restoring a profile re-introduces the problem, you will have identified the source and can remove it again.
As always Microsoft recommends a of your backup your registry before making any changes.
In a case of hardware failure we typically do not see the 'Initializing...' message. Check that the executable - 3dxsrv.exe - has permission to run in any security/firewall application.
If you are still not able to start the driver, our technical support
can help with individually looking at the things that could be blocking it.
