I solved my own problem by changing the SQL code in wp-slimstat.php for creating the wp_slim_countries table to the following:

$country_table_sql =
        "CREATE TABLE IF NOT EXISTS {$wpdb->base_prefix}slim_countries (
                ip_from INT UNSIGNED DEFAULT 0,
                ip_to INT UNSIGNED DEFAULT 0,
                country_code CHAR(2) DEFAULT '',
                CONSTRAINT ip_from_idx PRIMARY KEY (ip_from, ip_to)
        )$use_innodb";

Apparently MySQL 5.0.92 did not like the original SQL code and never created the wp_slim_countries table when the plugin was activated.
