Import multiple image folders in NextGen Gallery (nggallery)

I’m using NextGen 1.9.6 and I have a lot of folders (about 1000) to import with few images in each… And I want to know if there is a way to upload in one time few folders…
I find a topic on the wordpress forum (http://wordpress.org/support/topic/plugin-nextgen-gallery-mass-batch-import-or-upload) who make exactly what I want to do but it doesn’t work with my NextGen version (it’s working for 1.4.3 and a 2.7.1 wordpress version). When I go to the Add Gallery / Images menu I’ve got an error message “Parse error: syntax error, unexpected ‘}’ in /homez.312/unoeilqu/www/space-invaders/wp-content/plugins/nextgen-gallery/admin/addgallery.php on line 354“

Is someone has a solution ?
Thank’s a lot
