I am having a very hard time to generate a Gerber on some of my PCB's. When I click on Gerber Generator, it displays a Preview and I can click on the JLPBC button for manufacturing. However, once it goes there, it fails to import the Gerber although it shous that i t was a success, but it does not display thye PCB neither the board size. If I have that problem, the Geber viewer does not work either. So, this measn I cannot add PCBs to my cart for ordering.
