Jailbreaking 1.1.2 on Leopard

Hi there quick question. I jailbroke 1.1.3, but dl something from the installer that f'd my ipod up. Now here I am trying to jailbreak 1.1.2 on my ipod. When I dl jailbreak 1.1.2, the osx file is just blank white. And when I open jailbreak.jar it pops up and I select ssh and all that, then click jailbreak but a error pops up saying it cannot load iphuc. After I f'd my ipod up I had to uninstall my itunes and reinstall 7.6 could this be why? the biggest things is that the osx file is just blank white.

Thanks

again im on leopard.

anyone? got any ideas?
