I was working with a 3D file and I install an extension from the warehouse and all was ok. When I try to copy a component from another file the sketchup just have a bug. I had to close the file and now I can’t open the sketchup with the extensions… appear a window saying “Extension Warning” - “The sketchup bud last time trying open the extensions. Keep opening the extension? ”. But when I select opening, the sketechup just crash again 
Anyone can help me? Or maybe tell me how can I contact the support team?
