form can't update after its underlying query's underlying table are splited

I have a form D with its VBA code doing quotation. it is based on a
query C which is then based on 2 tables A and B.

Since table A is too big, and it contains data about 2 totally
different material, i split it into 2 independant tables, A1 and A2.
Then I updated the query C.

The problem occured: the form D which is based on query C can not
update recordset now.

Can anyone one tell me how to solve this?

thanks in advance
