Help in rectifying my database

[sdfaheem]

I tried delete the photoplog entries from the database and then i got this error:

Error at the line 198: LOCK TABLES `vb_adv_modules` WRITE;

Query: --
`vb_adv_modules`
--
LOCK TABLES `vb_adv_modules` WRITE;

MySQL: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'vb_adv_modules` -- LOCK TABLES `vb_adv_modules` WRITE' at line 2

I know i have gone wrong somewhere as i do not even have the basic knowledge of how a database works.
Its very tiring you know, every time i need to wait till the 65 mb file uploads.
Even the guys at vb.com suggested me to contact photoplog, but do u think will it be of any effect?
