Hi Roxanne,
How do you share the files? I would imagine that the file is
located either on your computer or on that other computer. There is an
easy way to check. Open the file on your computer. Once it's open,
go to File-Properties. The Location field will tell you where the file is
by giving you a path to its location. If that path starts with anything
other than "C:\" then it most likely is not on your computer and
you're opening it over the network (the other computer is acting as a server to
you).
If this is true and you find that the file is not on your computer, does the
other computer ever get any of these errors? If it does not then we know
that the network connection is causing the problem. You may need to get a
network technician to look at it. One thing that they will want to do is
configure the router so that it never closes the ports which Simply Accounting
uses (ports 13531 and 13541).
There is something that you can do yourself; do not leave Simply Accounting
running if you will not be using it for 10 min or longer. When you leave
it idle, your router can close the ports as it thinks that they are not being
used, and then this can cause errors once you go back to using Simply Accounting.
I hope this helps Roxanne!
