Hurray, it works.
Thanks for the help.
The medicine was following :
1. Install FW 1.05
2. Change Language with Easy Search 4.2.0.0 to Northern European.
3. Format the hard disk
4. Change Language in the Webb interface below FTP server to Northern European.
5. Done, start to put all data back from the back up.
Many thanks to you for the help to solve my problems, and a kick in the as for the Support team in Scandinavia for theirs proud, just stop reply my mail when they don’t have any more answer or ideas to dissolve the problem.
