Yes sure. I also wondered when I saw two purchase notifications in the same name and thought I will write to you that you are allowed to use 5 licenses anyway and so you don't need to purchase multiple licenses unless you plan to use at more than 5 machines.
Anyways, I have refunded the sale and you should receive the amount soon.
Please let me know if you face any problem.
Thanks for choosing Stockalyze,
