will be fixed and updated within tomorrow.

Yes, please delete old version before you install new.

As I see here http://octagonam.com/data-room/ , everything working as they should be.

that is not possible, you have list all items from any category or any tag, but no from a tag within a category, that will require good amount of customization in code.

Issue fixed and add-on updated, please download again to get the updated copy.

no such option, you need to edit code for that, however next update of the plugin will have the option to customize the window and post type options.

it could related with your theme or the page template you are using there, however I need to check it in your installation.

Please download latest version ( v4.2.1 ) from here: http://www.wpdownloadmanager.com/purchases/
