I am using Quicken classic Delux subscription for windows. I was starting to reconcile my account. It was reconciled without problems last month. After I opened the download from my bank, and verified all check amounts, I put in the closing date, the opening amount and then the ending amount. Instead of reconciling at 0, it was minus over $7,000. All amounts on checks were as the bank statement however, the amount in account was off. I have printed this account for years, as I looked back in the program, it has changed all the amounts in the balance column. None of the amounts have changed. The balance on 12/30/2013 is minus over $7.000, same amount it shows I am short this month. It appears that updating the program has changed all balances since I started using the program.
