It might be an idea to post the problem, because if there is a way round your difficulty, someone here will suggest it! Memory problems can be greatly eased by moving to a 64-bit architecture. Many modern computers are already 64-bit capable, and in that case, all that is needed is to change to a 64-bit operating system and re-install Mathematica. However, I'd start by posting your actual problem if possible. David Bailey http://www.dbaileyconsultancy.co.uk
