Error in AxdbUpgradetool


im trying to upgrade my 3.0 DB to a 2009. In ran the upgradecolumns and leftjustify procedures. Now I make an empty DB in SQL servermanager. When I run the upgrade tool I get this error:

Source db AXDB_GILL
Target db AXDB
The target db is not empty, UNICODECONV table does not exist: please check the db

when I make an empty DB using the Ax2009 installation wizard, I get the same error.

Whats going on here?
