Issue with importing texture

[hswick]

Total noob at Unity so this may completely be my fault. However, I imported the ragepixel package and made a sprite. When I go to click the animation strip Unity freezes. Console is giving this error:

UnityException: Texture 'spritesheet_1' is not readable, the texture memory can not be accessed from scripts. You can make the texture readable in the Texture Import Settings.
