Warning & Error in each matrix field

Hello,
when I create or edit matrix fields: warning
(wiget Tabble )
* warning: array_fill() [function.array-fill]: Number of elements must be positive in /var/www/html/drupal/cth/sites/all/modules/matrix/matrix.views.inc on line 38.
* warning: Invalid argument supplied for foreach() in /var/www/html/drupal/cth/sites/all/modules/matrix/matrix.views.inc on line 48.

This is an error with other matrix field (the same warning when create)

user warning: Duplicate entry '60-0' for key 'PRIMARY' query: INSERT INTO content_field_soluonghocsinh (vid, nid, delta) VALUES (60, 60, 0) in /var/www/html/drupal/cth/sites/all/modules/cck/content.module on line 1213.

What's happen?
Thanks for read!
