Good day, I'm developing myself in idestatic 7 demo for now, I'll probably buy the original soon, I was going to ask, when I try to open some projects that were originally drawn in the demo, it says "Incompatible file version. Use an updated program version to open this file." Do I need to install the ide8 demo or do I need an ide7 update? If ide7 is an update, where is this done? Thanks..
