Final Fantasy Hacktics

Hi. I'm at an impasse, since I followed the required steps (including Dslink), but I still get the Error 2 message whenever I try to open my file. I specifically made sure to put both files in the same folder, just to be sure. Is there a solution?

Edit:
nevermind I'm dumb
I got the right file this time.

Now, I get Error "Index out of bounds for length 1".

RE-Edit: Sorry. I blundered twice. I just had the European version without knowing.
