tool probe calibration vtc20

Between losing a board and a battery, I had to reinstall my parameters (M32B). I seem to have everything back to working, except the tool probe. I can go to MDI, and select Auto and tell it which tool to touch off, and everything goes fine, but the XY location that the machine positions itself to is no longer over the tool probe. I have gone thru my parameters very carefully and cannot find anything out of place, I have been thru the books and no where can I find a procedure to reset this location. Any help appreciated!
