I have several older programs (Calendar Creator, Cooking Lite) that have
worked fine before but all of a sudden I can't access. Here is the error
message I get:

>>C:\WINDOWS\SYSTEM 32\AUTOEXEC.NT. The system file is not suitable for
running MS-DOS and Microsoft Windows Applications. Choose 'Close' to
terminate the application.<<

It doesn't even let me re-load the programs. Any ideas? Thanks!!
