Solved Succecfully installed but NO kunena at components

I want to export only Kunena tables - Should I export all of them in one SQL file?

Mark only all Kunena tables, then scroll down and, at the dropdown list choose Export.

Thank you!
I exported kunena sql database
Then Uninstalled Kunena from Kunena component Tools
Now I was trying to to import Kunena database but it shows error.
Here is the screen of the error page:

it seems that when you exported the Kunena tables you also got something from joomla So do that again "database tables from your backup "and check only the kunena tables and then export 

I thought the same way and exported Kunena tables again. But the error still exists.
Maybe I should delete something?

very strange if you only exported the xxxx_kunena records and then deleted them from the database.
Then if you use tab import and use the correct kunena.sql file you should really succeed.
ps
if i see it right, it looks like you hks7d_action_logs selected and exported
those does not belong to kunena table so that must be it. s
o either you try again or you are looking to this hks7d_action_logs and delete only those
and try then import it again.
But always make sure you make a good backup of the Website first

Rich, please can you see the problem? I did import several times but the answers were always the same. 
Please!!!
