hi. sorry for my english. i'm from italy. until 2 days ago, Videostream worked good with mp4 files. since 2 days it blocks in loading. i tried to load same files i did days ago, but nothing works anymore. i tried to uninstall and install back. now i see the load blue button in italian, but no files working. thanks, giancarlo.
EDIT: i have a asus pc with intel i3 cpu. linux ubuntu 14.04. chromium browser
no native client plugin found, but it always worked without
