My guess would be that the software is trying to distinguish the computers somehow, maybe via netbios name. Have you talked to the vendor about the error?

So evidently the first instance of the app loads, but just as a second user tries to launch the app she gets the error "Cannot register station. 0xD", I'm guessing because port 139 is already taken, but it is still a wild guess. If that is the case, I ran out of ideas to work around this problem, so any help would REALLY be appreciated.
