AMDock macOS 10.13.6 issue

[houdini69]

After successful installation of AMDock I tried to run a re docking on AutoDock Vina but after setting Project (Project Progress 25.0%) and loading Target and Ligand with Prepare Input successfully I wasn't able to select Target option in Search Space area with an alert window "The working directory was not found or it does not have permission for writing. Please reset the program."
