I usually go onto Urban Rivals on a Mac, and I occasionally have this problem. I usually do not have the problem but either when my personal Wi-Fi network is getting high usage, or the Urban Rivals website is getting a lot of traffic, I cannot seem to see the home page. I am on Google Chrome.
Would you care to say which browser you are using?
