A minor update to the engine was pushed out today.

• International users commonly received an error resembling "There was an error when converting the date value '0001-01-01T00:00:00+02:00' in the field 'FromModified date' " when they performed their first sync.  This had to do with their international settings interpreting an empty date and converting it into a format that was unreadable by QuickBooks when looking for records modified since the last sync date.  With version 1.0.189 it will not put restrictions on the modified date if there has not been a sync completed before, avoiding the empty date conversion issue.
• When transactions were deleted consecutively in QuickBooks, you would see the sync engine commonly reporting that two or records were deleted at a time.  A fix has been made to only delete the most recent one, rather than attempt to delete this transaction and the previously deleted transaction a second time. 

To get the update either:

• Close the Method Integration Engine and run: http://www.methodintegration.com/methodintegrationenginev2/methodintegrationqb.application, which will download and install the update.

or

• Wait for a few days.  After 3 days of opening and closing the Method Integration Engine, the engine will eventually check for an update and install it.
