B.O.M.B. problem

Hello, I have been trying to migrate my BFD 3 account after deleting my hard disk. Unfortunately when I tried to download my Big Orchestra Marching Band it now seems to have two serial numbers where I only have one.
I can download the software but it doesn’t register.
My Fxpansion account is ‘cursors’.
Thanks
