I'm so sorry for taking so long to respond. I've been using several computers in this period of time, and finally I'm back with the original one where I have the problem. The problem still persists, even after all this time. I've made sure I have the latest version of flash player, and even tried deactivating AdBlock Plus. Nothing worked. I still get the blank page.
I'm attaching a few screenshots to give you an idea of what I'm viewing right now:
The first one corresponds to the blank page I got most of the times. No matter what channel I'm visiting.
The second one is an error message I get seldomly when I refresh the page several times. But generally, after a couple of refreshes, it goes back to the blank page.
Can I somehow fix this? Believe me, I've tried everything posted here. I even tried to look for that process in my task manager and it's not there. I'm using Windows XP Professional, and my default browser is Chrome. But I'm submiting this post using Internet Explorer, since I can't view the page on Chrome, as shown in picture Nš 3.
