Hello Aaron,
You shouldn't post login and password information on the forum, as it is public, even for a test installation.
I tested your install and on Firefox it's returning a zero sized reply, which used to be caused by PHP's memory_limit setting being too low.
You should have at least 64M set, as well as larger amounts for other limits (post_max_size, timeouts, etc).
There is plenty of info on
PKP's Wiki as well as this forum.
