Tnm7 has been working fine up until today. I tried to run the program and this window pops up that says

Command Prompt-TNM7
C:Windows\System\AUTOEXC.NT. The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose close to terminate application.

What the hell happened? How do I fix this?

As I had already replied via e-mail, this is something related to Windows, not TNM.

I had this once before on my wife's system after she updated her graphics drivers. The only thing that helped was completely reinstalling Windows as the DOS shell had completely been shot.

It can also be a multitude of things:
- a virus
- a worm
- a bad sector on your HD

Could you post your AUTOEXEC.NT? Maybe there's something in there which is killing the WinDOS subsystem.
