Still can't input serial code after following instructions

Hi,

I've just purchased your Migrate 5.0 software and I can't input the serial for authorisation. I have followed the instructions in the manual (Have IE11, W7 SP1, suggested ports open, FW security level set)

But it still doesn't give me a form to input the serial. Just a blank space.

This is very frustrating so any ideas in regards to a solution would be appreciated.
