After complete restore of data folder, things seem to be going well, but when trying to print any of the 'Purchase Order' group of reports from IR gives the following error:

"Add Node:: List Index out of bounds (260)"

Error repeats with 260 increasing one at a time until it becomes a 551

When printing the same reports from the old, replaced data, there are no errors

Transaction and Inventory Receipts reports seem to work.

Both data folders have the same number of IR*.* files so it doesn't appear to be any temp folders. Any Ideas?
