While I have only begun using wamp/php etc., and your post is a bit ah
sparse? I can suggest confirming the inclusion of the phpmyadmin folder in the document root. If you changed the default document root of C:\wamp\www\ during installation, then you will have to manually relocate \phpmyadmin and \sqlitemanager to your new document root. Doing so will restore phpMyAdmin functionality, assuming of course this was in fact your issue. The default documentroot folder tree should look like:
C:\wamp\www\phpmyadmin
C:\wamp\www\sqlitemanager
Now if you used the default document root, then perhaps you set the root password for mysql and can no longer log to phpMyadmin? If so, you need to edit config.inc.php (around line 74) and insert your password between the single quotes:
Line 74 $cfg['Servers'][$i]['password'] = ''; // MySQL password
You might want to have a look at "phpMyAdmin 2.6.4-pl4 Documentation"
