Database Errors?

[King Justice]

This is now the only database error I am receiving. I have updated to vB version 3.6.8 on the new server, so I guess this error is still coming from people who have not had updated cache to the new server?

I hope so.

Database error in vBulletin 3.6.7:

Invalid SQL:
SELECT COUNT(*) AS count FROM user WHERE usergroupid = 4;

MySQL Error : Can't open file: 'user.MYI' (errno: 145)
Error Number : 1016
