drupal-7.0-beta1.nl.po

Hi,

I am new to Drupal and I am not a programmer.

I am installing Drupal 7 Beta 1, first I tried to install drupal-7.x-dev using the drupal-7.0-beta1.nl.po,
because there is no language file for this release.
I am using Aqua Drupal Control Panel.
Both times there was the same error message.
I had deleted the drupal-7.x-dev before intalling the new one.
Both times the menu on the left side was correctly translated!
The installation stops at Vertalingen instellen(Configure Translations?)

Notice Undefined index: pt-nl in locale_add_language() line 390 of D:\druppie7b1nl\includes\locale.inc).
Notice Undefined index: pt-nl in locale_add_language() line 391 of D:\druppie7b1nl\includes\locale.inc).

SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'name' cannot be null

I went back in my browser and installed the English version.

Thanks,

Peter

My first impression, Drupal 7 looks beautiful
