Error saving grid

Have uploaded 2.5 version on Tools JX to my 2.5 Joomla site which I am upgraging from 1.5.27.

I have copied across the 3 grid tables into the j25 database.

Looking in the Grid controle pael and opening one of the grids I see that it is point at the old table, so I have now pointed it at the j25 table and tried to save and get this error.

in the page view I get this error message.
