i have alot of problems i know....

i cant log into runescape. i can get to the log in menu and the lobby but not the game itself. i just get a black screen and the music stops. sometimes the game does show up but it freezes immediatly. i have gone to tech support on the rs site and i did what they said to do for black screen. i cleared my jagex cache, i uninstalled and re-installed and updated java, i allocated more memory into java. the one thing i didnt do is one with the graphic cards but i dont think it'll help...this hasnt been happening until i updated my internet explorer to IE 9 yesterday. if anyone can help please do....
