Thanks for your help! Your explaination is very helpful understanding what causes the error message.

We kinda' new there was a problem with the code, but we are not getting any help from the vendor as to what the problem is.

The closest we got....
when the program tries to update an existing file that it needs it bombs. But when we remove the file it is looking to update, it creates a new one and updates that one just fine. The code written to handle the pre-existing file appears to be buggy.

Thanks for getting back so quickly
Regards~
