This is gonna sound a bit silly, but maybe you won't be able to use your physical legit copy for this?
It's still great that you bought it to support N+C, but for the English patch (and etc), you may need to resort to pirating it. Technically, it's not pirating because you own it, but you just can't use your legit copy...

Here's an Aarinfantasy torrent for the full ISO packaged in a RAR file. (Older version)
Once it's downloaded, extract it, and follow the instructions in the post I linked. Just don't patch the game with any of the patches, and move straight into the full English patch instead. The English patch is already pre-patched with the proper versions.
