full problems of importing.

I'm a new beginner in Drupal but I don't a good start with it.
I wanted to import a Mysql data (total of 500users) of phpBB2 into Drupal. I configured normally this module good in Drupal. Everything went fine till executing the migration.

==> Copy of the log.

I'm pretty confused so I'm thinking maybe mysql data of is wrong? I have installed a new phpBB2 v2.0.23 and I have the same problems as the first mysql data...
