Post Mass Additions performed with wrong date placed in service

Hello,

 We are closing our February Assets.  Mass Additions were loaded using ADI.  The accounting date was properly entered as 2/28/2009, but the date placed in service was 1/1/2009.  It should have been 2/1/2009.  The Prepare Mass Additions and Post Mass Additions functions were performed.  Depreciation was run with the period OPEN.  Depreciation expense in now too high by the amount of depreciation related to the February additions with the January date.  What is the best way to correct this situation?

Any help you can provide would be greatly appreciated.  This is delaying our month end close process.

Thank you.
