That might be the reason. I always thought I had to click the brush tool then click the thing to change the brushes then click the little arrow then pick Load Brush... So if I put them in that folder they won't disappear?
Yea you gotta put all your Brushes in this folder.. Reload Photoshop and they should be there in your brushes
i dunno never happened to me try and make sure the brushes were in the folder so that u wont have to load them all again
