Previously downloaded the shntool frontend and was able to generate shntool md5 files with it easily. Just went to use it again so I could seed another show here, and for some reason it no longer works for me. Instead of generating the shntool md5 file as it did before, now it is giving me a file with no file extension, and under file type instead of indicating it is an md5 checksum file it is listed only as "file". I uninstalled, reinstalled, and the exact same thing is still happening.

Same PC with the same operating system as before when it worked fine, so I don't know what is going on? Maybe some Windows update that I downloaded messed with the program? But then when I uninstalled and reinstalled that should have taken care of it... so maybe I just forgot one simple thing from when I used it before? Ideas? Suggestions?
