Restoring NodeTreeMaps

Hi,

I used NodeTreeMap in my Implementation. After my last mail, I tried  
to backup and then restore the database and I got the following  
InstantiationException while restoring.

Any ideas? I tried to rebuild my database to check for a problem in  
the database structure. But as you can see, this does not work at all.

I need urgent help, because this is a productive system, and now the  
nodetreemap does not work as I supposed it to work.

An error occured while restoring the database.
The database is not entirely restored and is probably not usable!
Please completely install and restore again.
