You'll need to find the code on the back of the installation booklet and enter that.

Here, the code found here:

Then, find the ones you want on the exchange, install them with the clean installer [if you have it], and then tell me which ones you didn't get that you want, and I'll see what I can do, kay?
Or if you just one one or two, I'll do them, just tell me which ones.
