thatys really really strange, ity should be blasting through the renders, incedentaly whats the scene file your using to test, one form zoo render?

now I dont know if this is the problem but I think that the processors are 64 bit, so your OS must be 64 bit too, is the version of may your running 64 bit also (I dont know if a 32 bit programm would run on a 64 bit machine though)
