Nevermind, i fix it, i just extract all the files in the same downloads folder, and then place all teh video files in the folder called "video". for some reason when i created a special folder for all the files in order to have a separated folder for this material i could not play the files, anyway i must leave the file unorganized but who cares if i can acces them.
This might happen to someone else so i hope this helps
running windows 7 btw
