Is there a way to revert to previous versions of Creality Print?
I have just installed CP Ver 6.2.1.3044 on my K1C and now for some reason the software keeps deleting all of my user presets when I close the program. 
I have spent hours calibrating for different filiaments and configurations only to find that all my work has been discarded.
Come on Creality, sort your sh%t out, it seems like every time you add an update to CP, you mess up other areas of your software.
You have some great products that are currently let down by very poor quality control of your software.
