Hi, I'm in an intro to maya class and I have my final due in a few days and recently each time I open up my maya room that I need to have done it crashes after the 2nd or 3rd render, I tried the previous 3 saved versions i have done, it crashed using maya and mental ray software, it never makes it past a 2nd full render, and then i get a beep and a fatal error has occurred.

So far it crashed on three different computers, all windows, 2 windows 7 and a windows xp. Its maya 2012 btw.

2 of them were recently downloaded versions of maya 2012 and 32bit versions

i uploaded my file to media fire here

its called next5.mb

if anyone can help ill be so thankful!

If its easier to send me back the file versus explaining step by step please do!

also I wanted to do the composite hotfix but i dont know how to uninstall the preexisting patch thats there, since when i try to run it it says its already there.
