this modelrole is also based in the AstorBase in the table Modelrole. So I think you delete a few entries here?
You could close AS, rename the AstorBase.mdf to maybe AstorBase_old.mdf. Also you had to delete the AstorBase.ldf and then you could start the Windows control panel,--> program/features--> select AS, press "Change" and in the following dialog use "repair". After this, you database should recreated. Start AS and have a look if the model role is working.
If yes we could have a look how we could bring it back to your "old" AstorBase
