2. Review the QBWIN.LOG file
Once the QBWIN.LOG opens, you will see something similar to the screenshot below. (Without the color-coded highlights)

The highlighted items in the screenshot above are examples of what you need to look out for:
The Type is the type of transaction – invoice, bill etc
The txn# is the internal transaction reference number (this is not the actual invoice/bill or other user-entered reference number)
The Date is the date of the Transaction. It may be shown in the USA or Australian date format
The doc# is the document number of the transaction
The Distrib accnt is an account used in the transaction
The $ is the amount of the transaction
The Other name is the name on the transaction
Use the information described in the log file to find the relevant transaction record in the Reckon Accounts data file.
When you have found the transaction, attempt to delete the transaction.
If the affected transaction is able to be deleted without experiencing a crash, then you can re-enter the transaction afresh.
If there are any transactions linked to the damaged transactions, such as a payment, then the linked transaction may also need to be deleted and re-entered as well.
