Queries :: Numbering Column Causing Query To Stop Responding

I ran some code to number old records in a column to order items in a datasheet subform however after updating the column in the inventory transactions table when opening the main form that relies on it. It runs a query to determine the customers balance due and the query for that is taking forever to run like 2-3 minutes or more however reverting to an old copy of the data it runs fine and all I did was renumber records in one column most of which had 1s in them the code to re-number the records:

Code:
Dim rst As DAO.Recordset
Dim i As Long
Dim OID As Long
Dim stringSQL as String
i = 1

[Code] .....

I continued playing with this today and the query that is breaking the 2nd level subquery that actually references the inventory transactions table that I changed runs fine but go up a level to subquery1 which references subquery2 and a sum of payments query and it chokes however sum of payments only refernces the payments table.

I did some more testing today Subquery2 and sum of payments query both run faster than what I can time with a stopwatch but when combined they take approximately 1:45 there are only 5 columns in subquery1 four from subquery2 and 1 from the sum of payments 3 of the first 4 are sum and the last is group by and then the one from sum of payments is group by

Subquery 2:

Code:
SELECT
CLng((nz([UnitsSold])*nz([UnitPrice]))*(1-nz([Discount]))*100)/100 AS [Line Total],
CLng([Line Total]*(1+nz([SalesTaxRate]))*100)/100 AS [Line Total With Tax],
[Line Total With Tax]-[Line Total] AS [Line Tax],
[Inventory Transactions].*
