Runescape not loading?

Heya all,

I have asked this question before, and have not been able to fix the problem.

Basically, when I go onto runescape I log in and all. Then, when I click "play now" (free version), the screen goes onto the loading screen then says that there "was an error with the webpage" and the screen does not load, it is just grey and frozen.

Does anybody have any ideas as to how to get around this problem?

Thanks in advance!!
