Permalink issue Error 404

Hello! I am sorry for a somewhat redundant post, I found similar issues in other posts, but for the most part couldnt understand the fixes offered as I am a WP/server seedling.
I just created 2 new pages, and they both show error 404, while all others work(site is set up to /%postname%/ permalink). if I switch back to default permalinks, all pages show fine, but moving back to /%postname%/ makes the 2 new pages error 404 again. I read about WP needing write access to change the .htaccess file among other things in WP codex but being such a newb, this might as well be greek. my htaccess file looks like this, which seems right –

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

any help is much appreciated, the more newb directed the better. Thanks! http://www.abishandmade.com
