Thanks but i have some problems. First I can't use mod_rewrite. I modified my .ht... and this is what i see when I active this option. "No input file specified"
And the second isn't important for use, but i don?t know how modify the code for my country "?????". This letters apears in URL's like a hyphen.
Thanks again!

EDIT: I fixed the second question adding 5 lines in functions_cseo.php.

$string = str_replace("?", 'g', $string);
    $string = str_replace("?", 'u', $string);
    $string = str_replace("?", 's', $string);
    $string = str_replace("?", 'o', $string);
    $string = str_replace("?", 'c', $string);
    $string = str_replace("?", 'g', $string);
    $string = str_replace("?", 'u', $string);     
    $string = str_replace("?", 's', $string);
    $string = str_replace("?", 'i', $string);
    $string = str_replace("?", 'o', $string);
    $string = str_replace("?", 'c', $string);
    $string = str_replace("?", 'a', $string);
    $string = str_replace("?", 'e', $string);
    $string = str_replace("?", 'i', $string);
    $string = str_replace("?", 'o', $string);
    $string = str_replace("?", 'u', $string);
