Movie not loaded..

Hello,

I'm running Win7 64bit , I have Chrome , Opera , FF , Safari and I'm able to view Youtube and Dailymotion and other websites videos just fine, but I can't view any video from that site

free after effects templates | after effects intro template | ShareAE

all the videos give a blank window and when right clicking I get 'movie not loaded..'.

I tried some old suggestions from Google like clearing cache and using Adobe uninstaller then reinstall flash player but they didn't work

Any new fixes for this?
