I had problems with Set Location before I figured out how to use it. You have to do one of the following to get it to update:
1. Specifically select the old connection on the top AND the new connection on the bottom and click on Update. This should update all of the tables. It's not enough to just open the new connection - you have to select it too.
2. Select the table on the top AND the corresponding table on the bottom and click on Update. This will update just a table.
