Missing column in PHPMyAdmin export

I exported a table from the server that looks like this...

CREATE TABLE IF NOT EXISTS `actions` (
  `aid` varchar(255) NOT NULL DEFAULT '0' COMMENT 'Primary Key: Unique actions ID.',
  `type` varchar(32) NOT NULL DEFAULT '' COMMENT 'The object that that action acts on (node, user, comment, system or custom types.)',
  `callback` varchar(255) NOT NULL DEFAULT '' COMMENT 'The callback function that executes when the action runs.',
  `parameters` longblob NOT NULL COMMENT 'Parameters to be passed to the callback function.',
  `label` varchar(255) NOT NULL DEFAULT '0' COMMENT 'Label of the action.',
  PRIMARY KEY (`aid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='Stores action information.';

However, I just reinstalled WAMP and when I export from there it looks like this....

CREATE TABLE IF NOT EXISTS `actions` (
  `aid` varchar(255) NOT NULL DEFAULT '0'COMMENT
) ;

This is missing all columns and I get an error when trying to import...

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')' at line 3

Should I be setting something here? I've installed WAMP a few times and the default SQL export has been fine. The database is exactly the same, the database on WAMP just ignores the load of columns and data when exporting. I definitely selected all table structures and data for export.
