updating/installing

So if anyone could help me that would be great… I’m pretty sure I just effed my wordpress page.

I was in my WP-admin page and saw the “update to version 2.6” at the top of the screen, so i downloaded it, unzipped, read the read-me; it told me to go to my home directory and delete all wp files except the ones changed, I did so, then put in the new word press files, “pointed” my browser at the wp-admin/upgrade.php and the blank web page with the wordpress logo came up… k so good right?

Well then I tried to log in and it didn’t work, so heres where I think I made a mistake; I re-downloaded WP v.2.6 and replaced EVERYTHING in my home directory with the new files and it asked me to set up wp-config.php like when I first installed WP! Then I tried recopying the files into home directory and now it does nothing… I type in my web address and just my home directory comes up with no wp files and I cant access WP-ADMIN!

please help! What did I do?/what can I do?/what should I do???!!!!

FYI– this was the first time I’ve tried to update my WP and I started this whole thing off pretty web stupid, and I still am but I’m picking up on a lot.
Thanks for any help
