BP Register page does not load

The BP register page fails to load since I changed the WP installation to a multisite install. When the site was first launched, the Register page did the same thing for a while, but seemed to fix itself. The login functionality seems to work fine. There doesn't seem to be anything in the forums that I could find on this issue, so any help would be appreciated.
