Hi Mireille,
I've moved your post into it's own topic. You need to send me the details as described in the
sticky topic you originally posted under.
Open your event log in windows and copy the details of the error message.
Also tell me when it occurs. Does it happen on start or during processing? At what stage of the progress does the error occur? Does it happen for every customer or a specific customer?
You need to help me help you.
Mick
