Technically, the MotoROS driver is independent from the ROS version Indigo, Kinetic...
So if everything was working, you don't necessarily need to update it.
But there have been improvement to the MotoROS driver, so getting the latest version is not a bad idea.
The error 8000 is probably the alarm 8000,"Could not save PARAMETERS file" generated by the MotoROS application.
We recently added some code for the MotoROS application to check parameters and modify parameters required parameters to operate ROS.
This feature is not available for all controller versions. I'm also wondering if you got the correct version of the MotoROS for your controller model.
Which controller (DX100, DX200 or FS100) are you using? and is the software version (SYSTEM INFO --> VERSION)?
Another possibility is that your controller was accidentally reinitialized or part of it was.
If you have a CMOS bin backup, I would start by reloading that.
