The PDF is clearly huge and Kindleunpack is not optimized at all for memory usage. You have two options to try:
1) If possible, install the 64-bit version of calibre and retry the plugin.If you have a newer PC with scads of memory, this is probably the way to go.
2) Install the 64-bit version of ActiveState Python 2.7.x (if you have a 64-bit machine--32-bit otherwise) and use the stand-alone version of KindleUnpack to extract the pdf from it's azw4 wrapper. This will at least let you leverage all the memory your PC has to offer KindleUnpack.

If neither of those works, then you either need a beefier 64-bit machine with tons of ram, or you need to buy smaller azw4s.
