On clicking Convert Project to PCB I get a dialog saying that element with prefix V4 and value 60 has a package named "NONE". However, the components list does not contain a part named "V4" and changing the package to something else is ignored by the program. Right now I'm stuck as I cannot convert my schematic to a PCB Any help is appreciated. Regards Found the symbol in another schematic I had in my project. Everything's fine now.
