Help Fixing An Error?

[Yukino_AE]

Ok, Hi!

I just recently reinstalled a fresh version of vb on my site. Everything appeared to be ok, all the tables installed in the DB correctly with the right prefix.

MY db is called aex4 and i use the prefix vb3_

So I have my forum board all set up, when I click on any of the forums to go to start a thread I get the following error

Database error in vBulletin 3.6.4:

Invalid SQL:
SELECT * FROM forum WHERE forumid='21';

MySQL Error : Table 'aex4.forum' doesn't exist
Error Number : 1146

It's like the system is trying to read the files without the prefix, as the vb3_forum file DOES exist (all tables do exist with my prefix) but not aex4.forum as that's my DB name. I have reviewed the config file and it is correct. Anybody have any other ideas on how I can fix this. I can't reopen my forum for live until this is resolved.
