Thank you very much Broni. I decided to ask help from Microsoft Tech Support directly instead. It's not that I don't trust you but it's just getting quite annoying when it's seem there is no explanation for my daughter problem. Everything works fine for my computer when going to those web-sites but not her
Last week it was working and then on weekend of 7-8 June, she went to visit her grand-parent and take a laptop with her. She try to use Internet there but have problem connecting with wireless router. So she didn't use it and when she came home and tried to use it that when the problem start. All others web-site work fine for her, she can visit any site she want to but only if whenever she want to watch something that need WMP plug-in then she can't.
Thank you anyway for your kindness and your time.
PS. Portugal lost last night against Switzerland, how can that happen?
