TvirtualTable260 savetofile question

I use virtualtable to manage some data and save them to a file. Saving/loading file works ok except in one case.
If i delete a field from the table and then save it, when i load it again sows the deleted field (in a DBgrid) without the values.
But i don't want the deleted field at all!
Here is a code snipet i use
// table.Fields[j].free;

What's wrong, please ?

    Field := VirtualTable.Fields[j];
    if Field <> nil then
Please try replicating it in your environment.
