Can't activate Metasploit Pro

[Isilme OrphousV <orphousv () yahoo com>]

After registration,I entered the product key and it said "Product Key accepted".And everything's good then.But when I 
click Activate,it said "Activation Failed: Product key is not valid" and by no means could I get it right.Is there 
anyone who has experienced the same issue as mine?
