I really wish you would abandon this v5 disaster. It is a horrible piece of software. It doesn't even detect Youtube videos. And any downloads i've ever tried to instigate always stick on 0%. v3.9.7, now that's a beautiful piece of coding. Thanks God for sites like oldversion.com and filehippo.com, ...

It isn't fixed in Build 1627 either, There were no non-western characters in the filename either. It was just a bog standard MP4.

Is FDM supposed to be able to preview MP4 files ?
Whenever I have tried, it says "Failed to open the file. Unknown Media Type".
