Issues with importing Brushes into Toon Boom Essentials

Hello all,

Recently purchased a Frank’s Animator Pencil for Toon Boon Harmony. When I try to import the brush into the program, it pulls up the dialogue box and everything goes normal until right after I select the file from my PC. The dialogue box doesn’t show any files, even though I selected them and they’re the proper format. I’ve read that Essentials doesn’t support certain brushes but also that it does? Just trying to find out what I’m missing. Thanks in advance!
