It has just come to my attention that DesignSpark PCB has released a new version, namely 7.1. Unfortunately, the website of DesignSpark PCB cannot be accessed at the moment. The soon as it becomes available again, I will install this new version and generate Gerber files from this new version. Hopefully the Gerber files from the new version will have no errors. As such, I do not require any action from you at the moment.
