Inventory out of balance

SOLVED

I have never used the inventory feature of Sage as I've never had a client that needed it.   Now one of my existing clients opened up a small shop.  I took all the invoices of the items she purchased and entered the quantity & value of the goods on the history tab of the inventory item.  I created a new data base file just for the shop to allow us to track the inventory and sales, but the deposits are going into her main bank account for her other existing business.  I will just be making 1 monthly entry for sales in order to reconcile the bank account.  I will also have to provide the accountant at year end the current inventory balance so he can make an adjusting entry.   All the purchasing of the goods also goes through the existing Simply data base for her current company.

The problem is the shop version is still in history mode and we are at year end and want to roll over to start sales in the new year but I am getting an out of balance error for the inventory.  Did I miss a step along the way when I set it up?  I thought entering the historical opening balances was all I needed to do to record all the existing inventory on hand.

I urgently need to get his resolved as they can't process any sales in the shop in the meantime as we can't change the session date to 2015!   We are using Simply Accounting Pro 2010 on Windows 8.
