I ended up doing a complete wipe, and fresh install of WP & BP again, only this time as you suggested I had the subdirectory folder all in lower case which became http://baskers.net/rickytweetup

Was having uppercase for the URL/subdirectory folder causing the issue?
– WordPress Theme Custom Community By ThemekraftVersion 1.15
– BuddyPress Version 2.3.2.
– WordPress Version 3.5.1
Again, I’ve tried it with just the default buddy press theme, and disabled all plugins and still can’t create new user accounts via the registration page.
