Hi there. I played ES2 up until about February of this year, and I don't recall any issues. I took a break from it, then picked it up again a few days ago. Since then, the game crashes almost every time I try to run it. Sometimes it crashes just when the progress bar on the loading screen reaches the end. Sometimes it crashes while I'm navigating the main menu. Sometimes it crashes within the first couple of turns. I haven't seen a consistent trigger for the crash. A couple of times, I was able to get further (turn 4 or 5), but eventually I'd get error screens saying the Galaxy failed to serialize and it couldn't save. Other times, it would let me click Next Turn, but production queues and the research queue wouldn't advance. I have tried uninstalling and reinstalling (though I did not delete data), I removed Registry.xml, I ran the .exe in compatibility mode for Windows 7 and as administrator. Nothing has resolved the issue. Attached please find a number of crash reports. Crashes.zip Please let me know if you need any additional information.
