SQL Nesting Logic Needed - sql

Question

I have a situation where I need to build a query that pulls gives me a list of member that used an item on their account in timeframe one but that did not use on item on their account in timeframe two.
SELECT DISTINCT SS.memid
FROM SS
INNER JOIN SSUSED ON SS.ssid = SSUSED.ssid
INNER JOIN MEMBERS AS MEMBERS_1 ON SS.memid = MEMBERS_1.memid
INNER JOIN PRODUCTS ON SS.productid = PRODUCTS.productid
INNER JOIN PRODUCTCATS ON PRODUCTS.productcatid = PRODUCTCATS.productcatid
INNER JOIN EMPLOYEES ON SSUSED.employeeid = EMPLOYEES.employeeid
AND NOT EXISTS
(
SELECT DISTINCT SS_1.memid
FROM SS AS SS_1
INNER JOIN SSUSED AS SSUSED_1 ON SS_1.ssid = SSUSED_1.ssid
INNER JOIN MEMBERS AS MEMBERS_1 ON SS_1.memid = MEMBERS_1.memid
INNER JOIN PRODUCTS AS PRODUCTS_1 ON SS_1.productid = PRODUCTS_1.productid
INNER JOIN PRODUCTCATS AS PRODUCTCATS_1 ON PRODUCTS_1.productcatid = PRODUCTCATS_1.productcatid
INNER JOIN EMPLOYEES AS EMPLOYEES_1 ON SSUSED_1.employeeid = EMPLOYEES_1.employeeid
WHERE
MEMBERS_1.siteid = #rvSite
AND SSUSED_1.usedate BETWEEN #rvStartWeek2
AND #rvEndWeek2
AND PRODUCTS_1.productcatid IN (27,28,29,58,77,75,30,61,31,32,47,68)
)
WHERE MEMBERS_1.siteid = #rvSite
AND SSUSED.usedate BETWEEN #rvStartWeek1
AND #rvEndWeek1
AND PRODUCTS.productcatid IN (27,28,29,58,77,75,30,61,31,32,47,68)
The issue that I am running into is that when I try the query this way I get the following error:
