clients info does not = current balance of prepaid deposits...

SOLVED

Hi,

I am at year end, and would like to close the history mode.  When I try to close, it tells me:

"The sum of your Clients' information does not equal the current balance of account 2460 Prepaid Sales/Deposits.

     -$310.16    Total Deposit and Prepaid Order
     $0.00    Current Balance of 2460 Prepaid Sales/Deposits
    _______________
    -$310.16    Difference

Either your Clients' historical information or the opening balance of account 2460 Prepaid Sales/Deposits, or both, is incorrect."

I have an accountant working with me.  Together we tried changing one of our client's opening balances by creating a historical invoice (June 30, 2013).  Then paying it off a few days into the new fiscal year (July 2, 2013).  This didn't work.  We tried all sorts of things for a few hours, and got nowhere. 

I called Sage, and they won't help me because I have the 2013 version, even though we purchased it 8 months ago. (Personally, I think tech support should be available for one year after purchase no matter what version you are running.)

My Data Integrity Says:

Deposit account Balance:  0                  Prepaid Orders/Deposits :   -310.16

How do I fix this? 

(And to make it more frustrating, my Simply keeps going to "not responding"  and I have to keep closing, and re-opening it.)


Please help me!

Thanks so much!
