I just starting experimenting with extensions and plugins and found Fredo6 offers many useful options. My problem is even though I downloaded the plugins directly from the Sketchucation Store in Sketchup 2019, whenever I start up Sketchup I get an error message that the Fredo6 Lib extension will not load because it is unsigned and then I'm asked if i want to load it anyway. I get this message each time i start up Sketchup. I've included a screenshot of the message.
Any help would be greatly appreciated.
