Use phpmyadmin and run a repair a couple times.

or

If you have ssh access to run mysql commands as the above remedy didnt work:
cd to you db folder - typically /var/lib/mysql/dbfoldernamehere
myisamchk -r *
myisamchk -o *
then run a repair using phpmyadmin

It looks like your autoincrement values are off. You can use phpmyadmin to examine the database and set the appropriate autoincrement value for the user table. Or the vbulletin team can do this for you if you submit a trouble ticket with a URL and login to phpmyadmin:

This is a typical issue after using impex to import a forum, the repair should fix the issue for you.
