Hi, I've run into a problem with the Auto-Router not wanting to route my PCBs and have tried several things to get an idea of where the problem be but the error only says "Invalid PCB" and provides no other details. On a new project ( [https://easyeda.com/jogra27/rob08-2019](https://easyeda.com/jogra27/rob08-2019), [https://easyeda\.com/editor\#id=\|1efb188a0f684e2990335294c224cea5\|dc3b7e3da87d4b9cacd177ce2a5c9458](https://easyeda.com/editor#id=|1efb188a0f684e2990335294c224cea5|dc3b7e3da87d4b9cacd177ce2a5c9458) ) I found that when I went to Auto Router I got an error "Invalid PCB" after pressing the run button on the "Auto Router Config" dialog box. Things that I have tried: * Cloud router * Local router v0.4 * Latest local router V0.8.10 * Different Arduino Boundary Outline I then went to a project that was auto-routed a year ago ([https://easyeda.com/Bentley2018/Arduino-Vehicle](https://easyeda.com/Bentley2018/Arduino-Vehicle), [https://easyeda\.com/editor\#id=\|9fdb3607968d4f6bba69d804c27ac139\|fcddf29f4e9740f29b32dd96674678d5\|ba17f10e355a498889e4dd45395b30eb](https://easyeda.com/editor#id=|9fdb3607968d4f6bba69d804c27ac139|fcddf29f4e9740f29b32dd96674678d5|ba17f10e355a498889e4dd45395b30eb)) and cloned the previously created PCB and when running the Auto-Router got the same error. I searched the forum looking for something else that I might try but have not found anything that would suggest why I can not longer autoroute these PCBs. Could you please suggest what I should do. Regards John
