General Mach Discussion / Re: Novusun, Win7 64 and Error 9991

That error code is usually related to a plugin. You can test this by removing each plugin, one at a time, from your plugins folder, and trying to adjust your motor tuning. If you are able to finish your configuration without an error message, the plugin you have removed at that point is most likely your culprit.
