Silent Autoupdate failed

Hello !

Everything was fine until version 19.0.0.185. After installing this version, the autoupdate don't work.

Nothing has changed in our infrastructure. We proceed like we do usually : deleting the content from pub\flashplayer\update\current\sau and putting the fp_background_update.cab content into. It was working well before.
