create dispmap crashes

I’ve search the forums to see if others have had similar problems but havent found any.

i downloaded Zbrush trial 3.1 and evry thing went fine, but as soon as i started trying to create dispmap for my model things didnt go so well.
Im not sure if its an issue with the program or my pc is not powerfull enough but as soon as i turn the dp subpix past 1 zbrush starts to create it and then freezes and i have to close the program

My hardware specs:

windows vista 32bit
quadcore 2.6
4gb ram

I would think my pc abe to handle the operation but maybe im wrong, if anyone has had a similar problem
