Robots.txt

I can't find the robots.txt file. It's causing the problem below and needs to be removed. Any help is appreciated.

Should the file be stricken or adapted to allow the crawler ia_archiver, crawling for the Wayback Machine can continue. Until then, the presence of the site is considered an express request to exclude the specified domain from the Wayback Machine.
