probs with WAMP re-installation

Hi friends,
i was using wamp and dreamweaver. created some testing db and connected but started having problems connecting with other db i created. I decided to unstall both the dreamweaver and wamp(i manualy deleted all relation files/folders). I have reinstalled wamp again but have some errors.

The first is from myphoadmin; <b>
The additional features for working with linked tables have been deactivated. To find out why click here.
The configuration file now needs a secret passphrase (blowfish_secret). i ve config.inc.php = <?php

$i = 0;

The second is
when i check at my php error log i get this pop msg with a blank notepad;
Cannot find c:/wamp/logs/php_error.log.file. Do you want to create a new file?
I have read a couple of forums but still can't resolve the problem.

I imported the phpmyadmin db and had this ( SQL Commands to set up the pmadb as described in Documentation.html.
--
-- This file is meant for use with MySQL 5 and above!
--
-- This script expects the user pma to already be existing. If we would put a
-- line here to create him too many users might just use this script and end
-- up with having the same password for the controluser.
--
-- This user "pma" must be defined in config.inc.php (controluser/controlpass)
--
-- Please don't forget to set up the tablenames in config.inc.php

CREATE DATABASE IF NOT EXISTS `phpmyadmin`

USE phpmyadm[...])

Plz i will appreciate it if your colective ideas can help me solve the problem asap.
cheers.
