I have been using CircuitStudio for some time now, and am doing the largest design I've done with the software. Suddenly, a lot of my components started giving errors when porting over to the PCB layout, saying "Footprint Not Found". When I open the details of the component on the schematic, the footprint details are grayed out, and I am blocked from adding another. I have had to recreate several of my components from scratch - sometimes triple re-create them - to get them to work. Others I can't get to work at all. And, to make matters worse, I am having the same problem with every Vault component I download. I am hamstrung by this problem and losing money as I write this. Please help.
