Upgrade error

Just upgraded to latest version and am now getting this error
on posting a message

Database error in vBulletin 3.0.6:
Invalid SQL: SELECT countexp FROM forum WHERE forumid='35'
mysql error: Unknown column 'countexp' in 'field list'

[Revan]

Fixed.

To fix this error, open newthread.php and newreply.php
Remove the following bits of code:

PHP Code:

    $expcount = $DB_site->query_first("[...]"); 


PHP Code:

 AND $expcount['countexp'] == 1

That now produces another error :-

Database error in vBulletin 3.0.6:

Invalid SQL: SELECT givepostexp, expperpost FROM rpg_battle_options
mysql error: Table 'thetechg_retreat.rpg_battle_options' doesn't exist

Bs. That code doesn't appear anywhere in my install instructions.
Redo the newthread/newreply modifications.
And check if you redid EVERY modification in the install .txt file (including templates) to avoid any future errors
