Forum Cannot upgrade from 3.8.5 to 4.03
 

I did a search and found a number of people with this same problem but they were not given any answers. I am running a 3.8.5 forum. The credits at the bottom show it too:

Quote:
Powered by vBulletin® Version 3.8.5

However, when I run the /install/upgrade.php script it goes to the /install/upgrade_360.php file.

Quote:
Your vBulletin version does not appear to match with the version for which this script was created (version 3.6.0 Release Candidate 3).

If you are sure this is the script you would like to run, click here.

When I click "here" I get this error:

Step 1) Misc Table Alterations

• Altering reputation Table (1 of 2)vB_Database_Alter: fetch_table_info() has not been called successfully.
  Table 'forum_new.reputation' doesn't exist

Any ideas of what is going wrong?

THanks
