Table 'admin_forum.ibf_core_store' doesn't exist in engine

I have problem with upgrade form 4.4.4 to 4.6.9. 

Table 'admin_forum.ibf_core_store' doesn't exist in engine
/var/www/forum.motocyklistow.pl/system/Db/Db.php::1928
SHOW FULL COLUMNS FROM `ibf_core_store`

Do you know what can i do with this error? Maybe i can create this table ?

rm -rf /var/lib/mysql/admin_forum/ibf_core_store.frm
