PC: adxencd.exe keeps crashing

I am trying to change the stage music. I followed all the directions up to dragging the .wav file onto adxencd.exe. When I do so, the little cmd window pops up, giving me all the copyright info about the program etc.

Then it crashes. That’s it. No .adx file or whatever you call it. Each time it opens, it crashes a few seconds later. I don’t know how to fix this. I did a search, but found nothing that helped. I tried changing the directory of the program, running it as an administrator, nothing worked.
