If that file is corrupt, they will need to manually enter the checks in BankRec. We are unaware of any BankRec problems trying to read this file when it is not corrupted - it may be faster to print the GridView results out for them and get them manually entered.

The next time your client posts AP checks, this file will be recreated. You may want them to make a backup of their data prior to posting AP checks, in case the problem re-occurs.
