Okay I seemed to have fixed it. Just in case anyone else has this problem. What I did was I renamed the sqpack in the Final Fantasy game files to old-sqpack. After trying to download the game again it made a new sqpack. Of which I tried downloading the patch again only to failure. So I then removed old-sqpack and left only the new sqpack in there. Tried again. Failed. I removed the new sqpack and put the old one back in renaming it to normal. Then it suddenly worked. I don't know why it works but it made it work.
