Whether using PB 12.5 .Net or Classic, the same problem exists which is this.
I created a new table then created a datawindow to retrieve data into and when I run the application, I get an error message saying it can't find the table.
However, I can retrieve the data using the Database Painter ISQL, when I preview the data in the datawindow and it listes the table when using the sp_help command.
Also, retrieving data from existing tables in the database work fine.
