Impex problem

[atlanx]

Hello, I'm trying to upgrade to vB from phpBB. I have installed the vB and it works. I have installed Impex but when I go to import/export in the admin cp I click on start module for

001 Check and update database

This is the error I get

ImpEx will now Alter the tables in the vB database to include import id numbers.
This is needed during the import process for maintaining refrences 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 origional phpBB userid.

The NOT lines are in red. After showing this for a few seconds it disappears and I have an option to redo the module but the same thing keeps happening.

Could someone please help and explain where I have gone wrong?

Thanks.

You haven't properly configured your ImpexConfig.php file, you need to edit the config file and add the phpbb_ prefix hhere it asks for a table prefix on the target data

In the ImpexConfig.php file the sourcetableprefix should be:

sourcetableprefix = phpbb_
