Membership New User Signup Error

I set up all my subscriptions and member levels and went for a trial run. I have the signup form set to popup which it does nicely. When I enter information into the new user fields and hit the Register My Account button the popup changes to an all white background with the following text:

Fatal error: Cannot use object of type WP_Error as array in C:Inetpubvhostsemma-land.comhttpdocswp-contentpluginsmembershipmembershipincludesclassesmembershipadmin.php on line 7294

I have tried repairing membership’s tables in the Options->Advanced tab.
