After Import -Threads are not showing as Newest First

[محروم.كوم]

I have checked another post and found to do this in Vbulletin Forum -

Part 1 -
Admin CP -> vBulletin Options -> User Registration Options -> Thread Display Mode -> Linear - Newest First
Part 2
To reset options for existing users:
Admin CP -> Import & Maintenance -> Execute SQL Query -> Automatic Query -> Posts - Newest First

Then click on 'Continue'.
Part 3
And finally to do this just for yourself:
User CP -> Edit Options -> Thread Display Options -> Thead Display Mode -> Linear - Newest First

I have done part 1 and part 3 but I am not able to do part 3. Please help . Its saying you are not allowed to do the function. Pls help
Can I do the part 2 thru phpmyadmin. If yes please tell me how. __DEFINE_LIKE_SHARE__
