Much apologies to those of you with older, 32 bit machines.
Though we recommend that you upgrade to a 64 bit operating system when you can, to get the best experience, we've fixed the out-of-RAM crashes that people with 32 bit operating systems have encountered.
You should now be able to play the game crash-free again:)
We apologize for this oversight.
This update has no effect on people with 64 bit versions of Windows or Mac.
