have you tried choosing option 2?
I think I figured it out, the file is being weird because I think I already had a 1.4 version and it replaced some of the files, but preferred the earlier 1.4 version? That's all I can really think of, because otherwise choosing option 2 was just going to a to be continued screen. Gave me a good excuse to sub to your patreon though so downloading a fresh copy from there fixed it!
