A while ago I downloaded Haze Light Demo and Haze Dark Demo, I used them a lot but today while looking for the fonts for my use, I could find them, I tried redownloading it but then I started getting an error saying: " light demo.otf is not a valid font file " Of course I realized something wasn't right, I tried using online converters. I tried installing it from desktop, extracting it. Nothing works and i'm really frustrated cause I always use the Haze fonts. Could someone please help me?

I thing (but I'm not sure) that your register base is corrupted.
I had that some years ago with WinXP.

I have the same problem, did you find a solution?

I sadly haven't found a solution yet. But i'll notify you if I do.

Try opening the font in a font editor and regenerate the font. That often fixes most of the problems.

As for availability of font editors, there are free ones out there. Do a web search and you will find one.
