I don't know how to solve it. Just did a research and found no answer.
I'll try later.
I'm sorry for that.
Update: The problem is in my computer as Mark has told me in a comment.
I'll download the thing that is missing.
Sorry!
Update2:
I downloaded and installed shokwave even thou it was activated.
The problem persists.
Update3:
Problem solved after disabling a plugin as explained in this site:
How to Fix the Shockwave Flash Error in Google Chrome.
