Impex from Snitz to vBulletin
 

I have a big problem with importing from snitz 3.4.03 to vbulletin 3.8.2

When click on 'Check and update database' i'm obtaing this message:

Altering tables

ImpEx will now Alter the tables in the vB database to include import id numbers. This is needed during the import process for maintaining references between the tables during an import. If you have large tables (i.e. lots of posts) this can take some time. They will also be left after the import if you need to link back to the original vB userid.

When I click on import then import vBulletin users 0 users. This also categories, forums, polls, discussions, etc. .. how to fix?

This is the configuration file:
