Crashes with C&C95 (TFD version), Why are they happening? Options

[insulfrog]

I am a bit puzzled at the minute with the crashes I'm currently having in C&C95 (TFD version).

The most common crash I'm having brings up a windows popup box saying: -
--------------------------------------------------------------------------------
The intruction at 004ce0cb referenced memory at 00000000
The memory could not be read from

Click on OK to terminate the application
--------------------------------------------------------------------------------
This one normally comes up as you just select a mission.

Another crash I'm having is a less common one, which brings up a windows popup box saying : -
--------------------------------------------------------------------------------
The intruction at 004ad351 referenced memory at 00000005
The memory could not be read from

Click on OK to terminate the application
--------------------------------------------------------------------------------

Other crashes simply freezes the game for no apparent reason.

Here is what I have done to try to rectify these crashes: -

1) Patched up the game to the latest official update
2) Patched up the game to the latest unofficial update (1.05 I believe, available from the forums)
3) Patched up the game to the latest unofficial update (1.06b I believe, available from Nyerguds)
4) Set compatibility mode to 'Windows 95', run in 256 colours, disable visual themes and disable advanced text services for this program

Has anyone else had these problems and can anyone offer other suggestions to get rid of these crashes?

Cheers
