I have done that, and when I click on the Key link on the buddyauth site while logged in, there are no keys displayed. Under the ACTIVE, UNUSED/INACTIVE, and EXPIRED columns, there are no keys.
I purchased the program today and have yet to recieve the email with my key. When I try to log into the home page it says that my username or password is not correct. Is the username for the forums and that login the same?
