Question users import from phpbb3 fails.

Forgive me, but Im strugling. I need to import my users, from phpbb3.
I manage to run the Kunenaimporter, and all data is imported, except the users.

I get this message:
extuser: Invalid query:
TRUNCATE TABLE `#__kunenaimporter_users`
Table 'vmobikwm_autism.ain_kunenaimporter_users' doesn't exist SQL=TRUNCATE TABLE `ain_kunenaimporter_users`

So I try to first create that table, but I fail to have correct structure in the table.

I try to follow the instructions, but Im stuck.
www.kunena.org/forum/203-Kunena-Forum-Im...Kunena-1-6?start=130

If Im to change the prefix in the com_kunenaimporter/models/export_phpbb3.php line #383 and on, please tell me how.
I wish there was a FAQ with solid description on how to do if you fail..



I moved my forum to under a 2.5 installation (not the 1.5) and truncating the tables and add all options. It seams to be working.
It says the database import of users is 100% done.

Is the issue fixed?

well
I will try to do phpb3 to kunena I stil did not do that
but since kunena are using joomla users you can import users from phpbb3 to joomla with jfusion
well you can import users from smf and other boards to joomla as well
