I have read that there exists a bug where loading a 0.9.1 game with the 0.9.2 client will cause this crash but this is not the case for me as I have been using 0.9.2. I have tried the 32bit and 64bit clients with the same results..
Here are the crash Problem Signature and config.ini

As a side note, I have been using Black Viper's Tweaked Windows 7 SP1 Service configurations, which has freed up system resources drastically. If you think some of these disabled services may be the culprit, just let me know:Tweaked Services
Since the save games are too large to attach, I have uploaded them to my Dropbox account. Saved Game: http://tinyurl.com/ntctws3

[EDIT 14-03-14 17:34] After some further testing I was able to get new games to save and load with no issues. I have removed the installed versions of Factorio and am using the portable versions. I'm not sure what was going wrong but hopefully it will be ok now. Still if these save games point to any bugs, I hope they help to resolve some.
