Hi Andreas,
An error message that contains something like 'field number is out of range' typically has to do with a mismatch between the data and the dictionary used for reading the data.
If you look in the \softrak\dict directory, you can find the Adagio Payables 8.0A dictionary files @P80AI.SSI and @P80AR.SSI. They should both have a file date of Apr 10, 2006. If they do not then you may want rename what you have and re-install Adagio Payables.
Have you installed any other upgrades apart from Receivables?
