There. Save after replacing.

Warning you again. I'm not entirely sure this will work. In theory, it should, but just to be sure, keep a copy of the original file somewhere safe. If this DOES work, the initial download screen should take 9 mins or so.

Doing this IS a risk, so play it as safe as you can. Perhaps wait until someone posts an actual link?

I just really hopes this works...

If it doesn't then that last guy who posted may be able to help better.
