backup-restore problem

[tsarinus]

hallo MySql friends..
I have a problem to restore my data on my local mysql-server.
i have made a upgrade from version 4.1.7 to mysql 4.1.11
My 4.1.7 was installed on c:\mysql, the upgrade changed this path to c:\program files\mysql. So i have to make a restore of all my data to this new path. (fortunally I have a backup). I'm using Mysqladministrator 1.0.14
Now it seems i have some problem's with this restore. i get alway's error 1064.

my mysql server is running. Just did some testing. i have create a new table test.testtable, when i make backup with mysql I get the message that the backup was finished successfully.When i try to restore this file i get the following message :

The mysql server returned this error :
Mysql error nr 1064 You have an error in your sql-syntax; Check the manual that con...
'testfield' int(10) unsigned NOT NULL auto increment

note :this message don't fit in the error window "con ... testfield ... is difficult to read)

Is this error in the sql-syntax generated by the msql-backup-tool ?
this is the backup-file:

SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT;
SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS;
SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION;
SET NAMES utf8;

/*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */;
/*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */;
/*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE=NO_AUTO_VALUE_ON_ZERO */;


CREATE DATABASE /*!32312 IF NOT EXISTS*/ `test`;
USE `test`;
CREATE TABLE "testtable" (
"testfield" int(10) unsigned NOT NULL auto_increment,
PRIMARY KEY ("testfield")
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
/*!40101 SET SQL_MODE=@OLD_SQL_MODE */;
/*!40014 SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS */;
/*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS */;
SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT;
SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS;
SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION;
/*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */;


What wrong with this ?
Thanks for your help !
