First, it would be best if you didn't used the "lime-green" color for your text, since it rendered the message quite difficult to read, so I've edited it.
In any case, I don't see what the problem is, of course you have to use the same code for 2 computers but, with 6 activations, it will be accepted on both so, please clarify better the meaning of your question and what do you mean with "get themback". The installer is always freely available, just install on each computer and register on each using your Serial Number.
