Drupal Community Portal

Hello, I want to update my Drupal site. I see all guides about updates but I have a problem when I migrating D6 CCK to D7 fields. In my site all fields are migrated. If I want to create a new content, they appear. But, for old content they don't appeared. My site can't upload a old fields. My content are empty.
I see two error message:
Warning: array_flip() [function.array-flip]: Can only flip STRING and INTEGER values! in DrupalDefaultEntityController->load() (line 178 of C:\xampp\htdocs\livesport\includes\entity.inc).
Warning: Invalid argument supplied for foreach() in views_plugin_query_default->compile_fields() (line 1101 of C:\xampp\htdocs\livesport\sites\all\modules\views\plugins\views_plugin_query_default.inc).

The last error I believe that it was caused by Views because I have any views when I use fields that it wasn't initialized.
How I resolve these bugs?
I hope that I was able to explain. I can't speak english very good... :P
Thanks you very much!
