I've had Java installed before, but I re-installed it just to be sure, and it still gives me that error. The version of Java of have is the latest one and I use Google Chrome, would that affect anything?
Hm...I have googled your error and got all sorts of links, each one with a different solution. However, I would suggest you redownload the cracked client, and dispose of anything belonging to the old (current) one on your computer.
Control Panel -> Folder Options -> View Tab -> Show Hidde Files Go to window's exploxer -> Local Disk (C:) -> Users -> Your Username -> Appdata -> Roaming
