Problem with WP 2.0.6 installation – I have no wp-config.php file?

I just installed (I think) WP 2.0.6 this morning. I made it all the way through the install page, and I got the following message:

There doesn’t seem to be a wp-config.php file. I need this before we can get started. Need more help? We got it. You can create a wp-config.php file through a web interface, but this doesn’t work for all server setups. The safest way is to manually create the file.

I checked the WordPress directory, and the wp-config file is there. Oddly, I noticed something else too, which is probably something I’ve done: Before installing, I could type in my address, https://spyderkl.net, and the blog came up. Now, I can only access the blog if I type in https://spyderkl.net/wordpress. Which is not such a big deal. However, when I try to access /wp-admin, I get nothing. Please help!
