Shades, after all you have gone through I think the best thing is to start over with installing KPro.
1. Run the KProID.exe program again (see your Download link email from the mtu.com store). If you cannot see your ethernet card in this programs' screen, your card is not enabled. I expect that is the problem. If so, reinstall the card and drivers. KProID.exe will find and display it when it is working.
2. Email your KPro MACID (for the card you want to run KPro with) to
dougd@mtu.com and explain that your first USB card did not work.
3. We will generate a new Serial Number for you and email it to you.
4. UNINSTALL KPRO from Control Panel, Add/Remove Programs.
5. Reinstall KPro and use the new Serial Number.
This should solve your problem and the System Error #1 message will not appear if it is solved.
