404 error

Just got my blog up and am already getting hit by yahoo slurp and googlebot. The only problem is that they check robots.txt, then visit https://spouse-catch-cheating.info/wp/wp-rss2.php and https://spouse-catch-cheating.info/wp/wp-rss.php

My server is returning a 404 error, and those two URL’s will not validate, however, if I enter those URL’s directly into my browser they appear fine. Both googlebot and slurp left immediately after getting the 404 error. Any help would be appreciated.
