(adsbygoogle = window.adsbygoogle || []).push({}); I am on rex 4.21 and I have tried installing coldboot files but whenever I open the coldboot installer I get the message saying that no files have been found. Anyone have any idea as I have exhausted all search possibilities.

Try plugging your USB Flash drive in the last slot (Slot furthest right) ^^

Yeah I have but still wont find them and the folder was "coldboot" no capitals still don't know.
