[Plugin: NextGEN Gallery] Wp 3.0.3 y NGG 1.7.2: Upload images and NGG show 0 picture(s) successfully

NGG Update to version 1.7.2 and since then I upload pictures or in HTML mode or flash mode, but after process load, NGG show message: 0 picture(s) successfully added. In reviewing the folders the images are loaded but NGG not attached to the respective galleries and if I push the button to check the folder for new images does not add any images.

I read in the forum, PHP memory limit should be 64 MB minimum, but in any case I wonder if that could be causing the problem. On the other hand checking the database found in the wp_options table, the value of ngg_db_version is 1.7.0 should not it be 1.7.2?
I also made a modification to your multisite.php, to correct problems loading images using Flash, follow the instructions listed in the track of NGG, whichever Alek Rabe reported in the forum:

This should fix the problem : https://code.google.com/p/nextgen-gallery/source/detail?r=896

In advance thank you for your cooperation and if Alex Rabe read this track I’m at your disposal to make the necessary evidence.

Greetings from Peru.

PD: how I can downgrade NGG to version 1.6.2?
