esther

Hi I bought this product a long time ago but only installed it today.  I just noticed dthat one of the fonts isn't working.  HB Sketch.otf

I installed other fonts of his to the same place in my fonts folder on my mac including onen with the same file name extension and that onen works but the HB Sketch.otf

does not show up in photoshop.

Any ideas?

Love esther
