Pro Sites Registration Conflicting with Membership2 Pro Registration

Hi,

I just upgraded from Membership Pro to Membership2 Pro. It is activated site-by-site. This way each site can have it's own members and permissions. I also have Pro Sites network activated so visitors can subscribe and create new sites.

When a visitor to a sub-site tries to Register as a Member to the sub-site, they receive first the Membership levels available page, then going forward they receive a Registration page with both the Membership2 and Pro Sites registration information.

Also, I'm using the Terms of Service Plugin. The TOS info also appears twice on the Registration page.

There is also an Anti-Splog plugin conflict as this error message appears at the bottom of the page:
"Fatal error: Call to a member function get_error_message() on a non-object in /home/theweeb/public_html/wp-content/plugins/anti-splog/anti-splog.php on line 1582"

Any suggestions?
Thanks,
Chuck S.
