Setting virtual memory progrmmatically

Hi
M5drvr32.exe is not installed as apart of Macromedia Director. It is
independent.
We are using MMPOpen() is is a wrapper arround director interface.

We are getting the same error when we run M5drvr32.exe interactively.

We are using M5drvr32.exe version 5.0. Do you know where we can get the
later version.
I didn't get in net.

Regards
Sudesh
