New User treated as “Pending” when “Active”

Hi, I am test-driving the free version with a view of upgrading if everything works as described. However, new users (affiliate registrations) are prohibited from logging in to their Affiliate Dashboard and are presented with the Error message that their account is still “Pending” when they are showing as “Active” in my Admin backend. Further to this I have it set that all new Affiliate registrations should automatically be Active so at no time should anyone be marked as Pending. Please help. Thank you
