Pointing to the correct post from old links

[Brew]

I have several sites that I am consolidating into one site. There are links to my forum all over the net that are not correct. So I am getting hit with hundreds of DB errors an hour.

If you go to this address, which is one of the links giving me fits, you'll see the error page.....

And this is the link where the actual thread is:

http://www.pcgnetworks.com/forums/showthread.php?threadid=53

The email I am getting is:

Database error in vBulletin :

Invalid SQL:
SELECT title, data
FROM 1vb_datastore
WHERE title IN ('options', 'cron', 'forumcache', 'usergroupcache', 'stylecache')

mysql error: Table 'pcgn2_pcgnforum.1vb_datastore' doesn't exist

mysql error number: 1146

In that error it says "mysql error: Table 'pcgn2_pcgnforum.1vb_datastore' doesn't exist" I don't know why it is trying to use 1vb_ as the table prefix as the good url is using the correct prefix.

Any ideas what I can do to get people pointed to the right thread....and relieve me of the hundreds of DB error reports?

Thanks!
