Have you contacted Viking? You probably need an upgrade to the software so that it can talk to your new computer. I'm guessing you went from an earlier version of Windows to Windows XP or Vista?

I had the same problem with my Amazing Box and just last week downloaded the software upgrade (it was free) and now it works great! (Better than before, actually.)

LPT is a printer port, the really long, wide ones. It sounds like the software is looking for old computer parts that don't exist! (My old Singer EU won't run without a COM port, which most new computers don't even have!) If you have a friend with an old PC in their basement you could ask to use it and run the software on a machine that's old enough to be compatible with it. That's what I did with my Singer until I got my Viking machine. You'd have a dedicated "sewing design" computer.

I have the same problem! Were you able to resolve this issue? Trying to run Customizing 1.2 on windows xp...I can design the monogram but can't get it from the computer to the programmable card due to the error msg 'no lpt port available'. I'm not spending hundreds of dollars to monogram a dozen towels so new software is out of the question. Thanks!
