Visualizer starts up, but when trying do an Open/Place from Shapes you receive the following error message: "The central Shapes data folder is invalid or could not be created".
The central Shapes folder (Users/Shared/EskoArtwork/Shapes/) must be present and should have read and write permissions for everyone. It should normally be auto-created by the software, unless the current user doesn't have the proper permissions on his/her shared folder. In case the folder is not present, create it manually. In case it is present, make sure that you have both read and write access to it.
