I upgraded my computer from Windows 8 to Windows 8 PRO. Everything works fine except one problem. I would like to watch a lecture. the problem is that I can downloaded a lecture and watch it with the external player provided at the site, but I can watch online. The lecture will not open on their website. What is the problem? Is this issue my computer or their website? I have watched the lecture with my xp before, everything is ok.
Please advice. Thanks for any reply.
