in your local DW site that you are working with do you have a connection to your live db? Based on the recordset having the exclamation points, the DataAssist server behavior taking a while to load and the table not being present it seems that you might not be able to connect to the db directly from within DW.
As a test of this I opened up my products insert page and edited the Insert Record server behavior by double clicking on it in the server behaviors tab. I was able to interact with the local PowerStore DB without issue.
