Hi Sinziana
Your question is surely genuine, but do not belong to this forum "Hardware and Performance", I'm afraid.
I have no clue about Articulate presenter but I guess it generates Flash animations. In that case read http://docs.moodle.org/19/en/Multimedia_plugins or http://docs.moodle.org/20/en/Multimedia_plugins depending on your Moodle version. Moodle 1.9 and 2.x handle video differently.
Then use the "advanced search facility" mentioned in the introduction to this forum to find out the correct forum. Once you repost the question there, send me a message so that I can delete this discussion.
