Let try to explaine it:

Now the programm is working fine, but I have only Englisch installed.
Now I do the next steps:

1. Uploading the phrase.php file
2. Uploading the upgrade.php
3. Run the upgrade step and choos for import the language strings

After run this I get this error:
Preparing to update database...
Error performing MySQL command: INSERT INTO cp_languages VALUES (2, 'Dutch', 'NL', 'UTF-8', 'ltr');
Error: Duplicate entry '2' for key 1

Error performing MySQL command: INSERT INTO cp_phrases VALUES (1, 'admgrp1', 'Global Options', 'Global Options', '2');

Error performing MySQL command: INSERT INTO cp_phrases VALUES (5, 'admgrp5', 'Show Ad Options', 'Show Ad Options', '2');
Error: Duplicate entry '5' for key 1

after this I must install the whole scripts again, because I get a blanc page

So what do I wrong????
