1) Yeah, they are from a while back. Version .30 added the ability to change playbooks and the depth chart setup (3-4 to 4-3 and vice versa) while version .19 added the ability to edit the head coaches names and run/pass ratio. However, neither one allowed PS2 files of any kind to be edited. The only version that includes that is version .41 which Finn released last September. And that one does allow PS2 max drive files to be edited and loaded in-game. In fact, the latest version you have is the one that the other guy is looking for (but already found).
2) I have no idea why you're getting that error. All I know is that you cant upload the actual application as is because OS will say that its an invalid file which is why I zipped it and for those who need / want that one, they just need to extract it.
