Make sure you update your SQL with any changes that are required that happened since your last revision. Here is the SQL folder from the SVN:
http://code.google.com/p/projecteqem.../utils/sql/svn

Here is the particular SQL file that you need to source for that error:
http://code.google.com/p/projecteqem...endeduntil.sql

This is the actual SQL line from that link:

ALTER TABLE `account` ADD `suspendeduntil` DATETIME NOT NULL;

Also, when updating, make sure you read the changelog.txt file and check for any quick SQL stuff in there too. Sometimes instead of making new files in the SQL folder, people just paste the line right into the changelog.
