Xirus plugin problem with toolbar Icons

Hi Forum, I looked for a way to contact Xirus , but couldn’t find a place. Anyway, I am trying out Xirus and after loading it into Rhino5 I have lost all toolbar Icons. You can hover over the blank buttons and still get the text. Anyone know of a fix ? Thanks, Mark
