Writer loads as a blank page.

Hi, I'm new to zoho but I liked the idea of an online wordprocessor that I can use from multiple computers. I signed up a few hours ago while at work where our computers use Linus Ubuntu and a Firefox browser and the Writer came up fine. Now I'm home and using my Windows machine with Norton Firewall and Firefox and the writer opens as a blank page. I've checked my security options in both Firefox & Norton and I have received all the cookies from Zoho. What gives?
