Unhandled exception

[Glenn Massey]

I keep getting this message, any ideas what it would be? 

The AutoCAD files generally seems fine to work on.

Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

32-bit or 64-bit?

When does it happen?

[Glenn Massey]

Roy,

Its a 32 bit setup. It happens as soon as I try to render.

I was thinking the computer maybe can't handle the model.

Regards

Glenn

You're very likely bumping into a 32-bit limitation.  See here for some ideas.
