Supporter option not visible

OK first off, I could not install the Supporter 2.0.8 plugin with the "add new" upload feature. It uploads fine, but when I activate it I get a this error

Plugin could not be activated because it triggered a fatal error.

I then did the install manually, and the supporter plug in shows up on my "site admin" menu. But not under the plugins "installed" section ?

I can configure everything, save it , and edit all the features in the wp-admin console. But this is odd....

I am using BuddyPress Social theme, and when i go to register a new user there is no visible Supporter option.

I noticed that some reason BuddyPress Social rewrites the URL of the /wp-signup.php into /register

Can the theme be messing up the supporter option?

I am using WP 2.9.1 with BP 1.1.3

I have deactivated all the other plugins and I am trying to make this work. Help please.

TIA
