Does the database fail to load in the game or in the editor?
Could you make sure that you have the latest patch installed, you can find a link for the latest patch in the General Questions forum.
If installing the latest patch doesn't fix the issue, would it be possible for you to upload your database to our ftp server, so that I can have a look at it and try to figure out what has gone wrong. You can find details on how to upload to our ftp in
this topic, before you upload the files please make sure to zip them all up into one file.
