Lost all datatypes to "unknown"

Question

Hi,
i am working within a Relational Model. ~30 tables and a Physical Model. After several changes all datatypes are gone now. Every Attribute has Datatype UNKNOWN.
I going to reverse engineer the whole stuff from the database now. But i think this is not expected behavior.
Another thing is, while reengineering some objects from a different schema into my modell, the IDE freezed and didnt come back. Had to kill it by Taskmanager. Result was, some Sequences in the Physical Model were deleted from the model. The files are in the model structure on disk, but Datamodeler does not recognize them anymore.
Working on Windows 7 64bit.

Hi
if you see them in directory structure then find file Objects.local related to your physical model and rename it. Start data Modeler and it'll recover it - your sequences will appear.
After several changes all datatypes are gone now. Every Attribute has Datatype UNKNOWNHow they were defined - using domains or just logical types. Do you see these domains / logical types in your design?
