ODBC PostgreSQL: Data Source Error "Object not found"

ODBC PostgreSQL: Data Source Error "Object not found"

Hi Community
We use the DevArt ODBC PostgreSQL Connection on a daily base in order to connect Microsoft Excel directly to our Postgre-DB. All has been working fine until a few days ago.
If I try to use an existing connection or create a new one, regardless of the query, I receive the following error:
[DataSource.Error] ODBC: ERROR [HY000]  [Devart][ODBC][PostgreSQL] Object not found

I already:
 - updated the Devart component to V4.4.1
 - completely re-installed the component

Any further advice would be very much appreciated.
