Jill:
What version of Payables are you using? Is this the first time you've run the Data Integrity Check since you upgraded? There's a very good chance that those errors are unrelated to what you experienced. Could you use the mouse to select those errors, copy the highlighted block (using [Ctrl][C]) and paste it here? The Data Integrity Check has recently been upgraded to flag things that it used to ignore before. If that's the case, the messages can be resolved by using the "Rebuild" button.
