Hi David,
<< Invalid Normal Array >>
It sounds like your 3DS.EXE got corrupted somehow. First, check your
system for virus' that might've "touched" the program, and then
delete your 3DS.EXE and reinstall it from the original master disks,
making sure that nothing modifies the program in any way. If the
problem continues after that, contact your dealer for a new set of
disks.

This is a symptom that something has corrupted your 3DS.EXE file.
First, check your system for viruses very carefully. Then, once
you're absolutely certain that you're virus-free, reinstall the
software from the master disks. If the problem persists after that,
go back to your dealer and get another set of master disks.
