Hi Isaias! Have you made sure the files are unblocked? Check the first video https://thinkparametric.com/courses/create-custom-view-filters-using-dynamo/videos/210 @4:50. This package is (very) Beta so there might be some bugs, feel free to send Konrad a message on the Dynamo forum https://forum.dynamobim.com/ and don't forget to add the #archi-lab and #thinkparametric tags to your post. Good luck!
