I have been trying to get on battlenet for ages I have downloaded the file from this site, but I can only patch my version to 1.09 and not 1.09b is this why the battlenet patch won't work? How can I get onto battlenet????
I reinstall then with the original game exe. I patch V1.08 then V1.09 then when I try V1.09b it says it's for a different version or something then I try battlenet ck and it downloads 100% then tells me somethings wrong! Where am I going wrong someone please help, thanks heaps.
P.S what does no cd mean? sorry for the dumbness.
