Thank you for your post. Is there any warning/error message show on the screen so that we can know more about the problem? Besides, could you post here a screenshot of your database configuration dialog box? Thank you.
About the problem of importing Erwin file, could you send me the XML to have a try? I suggest you not to post the XML file here as it may contain some private information. You may send to my email box directly Here is the email address: jick@visual-paradigm.com
