There is a similar post further down the page, but mine is slightly difference hence the new thread.

I'm trying to enter calibration data for two EIO inputs. The first is a linear graphed AFR, the second is a non-linear fuel pressure sensor with individual points.
I enter all my points, save the .cfg file and can log accordingly in each instance. The problem is after closing the scanner and reopening, it loses the calibration points for one of the inputs. It never loses both, and there's no rhyme or reason to which one it deletes. I've re-installed the entire VCM Suite 3x now over the course of a month using different builds, but the problem comes back every time. Am I just plain doing something wrong?
