Play runescape Black screen

Im here reportin that black screen when i try to test html5, 1 month ago i played in the beta html5, and i have 2 weeks with this problen, and it finish the pre-loading map.

i just log into the game with account and ********, and all the screen turns into Black screen just with the box “pre-loading map” i can wait 15 minutes and the screen still there, im writing this with another window trying to play html5 hoping it fix, but i see the same screen.

I have reported this lots of time and no fix, i have reported also in the spanish bug report.

Thanks.

NOTE: the screen is only when i go to lobby, recently the cliente kicked me to log-in page and it was normalyy with the background and all that things.
