Hi,
I'm having a database problem when updating from vb 3.6.0 to vb 3.8.6. I'm experienced with database errors and management and I am unable to interpret it myself. Any help at all would be appreciated!
Below is the error message.

Database error in vBulletin 3.7.0 Beta 2: Invalid SQL: ALTER TABLE groupmessage
CHANGE groupid groupid INT UNSIGNED NOT NULL DEFAULT '0',
CHANGE postuserid postuserid INT UNSIGNED NOT NULL DEFAULT '0',
CHANGE postusername postusername VARCHAR(100) NOT NULL DEFAULT '',
CHANGE dateline dateline INT UNSIGNED NOT NULL DEFAULT '0',
CHANGE ipaddress ipaddress INT UNSIGNED NOT NULL DEFAULT '0';

MySQL Error : Unknown column 'groupid' in 'groupmessage'
