These FLEX LMs are always a problem.

I guess, the license isn't bind to a physical dongle on the parallel
port. So one can conclude that the software tries to read the MAC. This
probably happens in a NETBIOS.DLL call which then probably calls the
NETBIOS.VXD.  I propose you run with --debugmsg +relay,+snoop,+vxd and try
to decipher what is going on before that failing VXD call. In the easiest
approach, you can build a fake builtin NETBIOS DLL, with the appropriate
function returning the MAC in the first approach hardcoded or really reading
it with OS calls.

If running with --debugmsg +snoop crashes, I have a hack that may help
there. I have also patches for an empty NETBIOS dll.

However I guess that this probably isn't enough to make FLEX LM happy.

Bye
