Try to do the following.
First open up a dos command box (Start - run - command or cmd followed by enter), give the following command:
ping "ip address of the qm.net without the quotes" -t
This will send every second a package to the qm.net which should respond to it.
Let it ping for about 10 minutes or more before starting the software.
You want to know if this happens only whith the qm.net or only when you start the software.
Now start working with the software and wait until the message appears.
As soon as it shows up, switch to the command box and check if it really lost it's connection.
If so, try to disconnect the cable and plug it back in to see if the link will come back?
(To stop the ping: ctrl + c)
Is your qm.net connected by a direct cable or trough a hub/switch?
Try it without the hub/switch
Try to update the latest drivers of the network interface in your pc's.
Try to set the speed of the pc's network interface to 100MB full duplex, this seems to give more problems lately with older netwerk interface cards wich only support 10/100mb line speeds.
When this isn't solving the problem, you might could switch the qm.net with someone and see if this solves your problem, if so your fine and your friend has taking over your problem
Or take it back and give pangolin a e-mail.
