Setup went fine, all the admin stuff works good, but can’t view site???

hello,

things went fine on the “install” but when i click view site from the admin screen, i get errors like:

Warning: main(./wp-blog-header.php): failed to open stream: No such file or directory in /home/revoweb/public_html/wp/index.php on line 4

Fatal error: main(): Failed opening required ‘./wp-blog-header.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/revoweb/public_html/wp/index.php on line 4

any ideas?
ps i did install it in a folder labeled wp, not wordpress

thanks!
