WordPress database error after fresh install

I just downloaded and activated your version 1.0.0.

I added the shortcode [ewz_show_webform identifier="pair"] to a page and tried to upload a new image. When I clicked the Submit button I got a dialog box that said (in part) “WordPress database error [Field last_change doesn’t have a default value]” and “Sorry, there was a problem creating the item …”

I made a change to the save() function in ewz-item.php that avoids the error:

} else {
//                $data['upload_date'] = current_time( 'mysql' );
//                array_push( $datatypes, '%s' );
                $data['last_change'] = $data['upload_date'] = current_time( 'mysql' );
                array_push( $datatypes, '%s' );
                array_push( $datatypes, '%s' );

                $wpdb->insert( EWZ_ITEM_TABLE, $data, $datatypes );
                $inserted = $wpdb->insert_id;
                if ( !$inserted ) {
                    foreach( $this->item_files as $item_file ){
                        $errors .= $this->delete_file( $item_file );
                    }
                    throw new EWZ_Exception( 'Sorry, there was a problem creating the item '. basename( $item_file['fname'] ) .
                                             ", please refresh the page to see your current status.\n", $errors );
                }
            }

As you can see, I commented out two original lines and added some code to supply a value for ‘last_change’.

I also had a problem with the “Example Competition Form”. I selected “Digital”, supplied a title and clicked “Submit”. I got a dialog box that said “Sorry, there was an error in row 1: A Digital type must have an Image File.” There is no visible field on the form where I can supply an image file.
