Man !! I went through hell for 2 weeks trying to figure out why JAVA would not work. I was using JAVA version 6 update 26 and I update it to 27 and that was when everything went downhill from there. I ended up being force to install JAVA version 7 and finally I was able to access my yahoo games. Well, Java version 7 update 1 came along and it broke my games again. I was getting "Error 26011: Unpacking rt failed" when I install java but at the end of the install it said that it installed successfully. Finally on JAVA site it mention that it might be antivirus software and so I shutdown ONLY WSA and I got no error message on installing and I was able to access my Yahoo games again.
