Please try to clear ~/.arista/presets and then re-run Arista. There was a mistake I made a long time ago to not check for PNG along with SVG images for presets in the simple update code.
This has been fixed by removing presets that require PNG images from the auto-updates and by adding the PNG check in http://github.com/danielgtaylor/arista/commit/72f47ce8b885642a7341c51fdedf8977ef40993a
