First, thanks for providing this tool. However, I just upgraded t the most recent version of Kicad and nothing seems to work. My schematic, that was fine in 4.x (in fact I got gerber file and pcbs from the data). I now get a library error and my schematic is filled with question marks. It seems all links to libraries are gone. The links are missing to my custom parts as well as standard parts like resistors and capacitors.
I am afraid to open any other schematics because of these issues.
Again, thanks for your efforts. Please advise.
