Roy,
Just confirming: at this point, if you use 4.0.1 – everything is fine. But if you use 4.1m1 – nothing works? (I’m trying to rule out changes to your Database as an issue)
Could you please verify your connection strings and driver / profile setup in 4.1m1 and make sure it’s all good and identical to 4.0.1?
What happens you expand a table in 4.1m1 in the DB Browser, do you see the PK annotations? Also, could you please follow the instructions here: Posting Guidelines, I’m especially interested in your error log for clues as to what might be going wrong here.
Best,
Brian.
