I agree... i could not find line 1875 in winqry either...
But our error routine captures the error details and is send to us via email.
Here is the captured error details:
Error#: 42 Error #42: Subscript out of range/Invalid subscript

I have sent them upgrades that will refresh all the PVX programs and our applications programs.
