I have 6.0.6 and its the following error
"OK, I see. This is a bug that i have logged, it should be corrected shortly, it should allow for the use of your own table instead of forcing one of the presets. I will let you know an update is available to correct this."
In the check out wizard on the orders tab under database heading it says if i deselect a check box i can use my custom database instead of the presets. However i have no check box to deselect.
