Unable to Load Game File

Description

This has happened to both me and my friend playing side by side on different systems. Both of us are Running Windows Vista on modern machines. Both were in simataneous movement games. Both were utilizing Unnamed's AI MOD. On his game SEV stopped responding while processing turns, he had to close SEV through task manager and then popped up with an invalid pointer operation. Upon restarting SEV he was unable to load that game file (and also was unable to load a seperate game file save (about 10 or more turns behind). He was over 350 turns into the game large cluster galaxy. 4 players total: 1 human and 3 computers, combined total of about 1600 ships and many more units.

My issue was less eventfull, After seeing this I was careful to make seperate saves every few (3-5) turns (in hope that he did something wrong and my backup would be able to load (as it should). Everything was going fine no problems (at one point in time I had a crash when looking at comaprasions but no big deal, it worked a few turns later after a SEV restart) after 3-4 late night game sessions with about (estimated) 150 turns in I used the GUI to shut down SEV and everything was fine, started it up the next night to "unable to load game file" as well as the backup file I made too (2-3 turns behind the current game) Both methods for lodaing didn't work (Resume game/Load game)

I don't need to tell you how frustrating it is to being playing such an immersive game where you put yourself into your Empire to live it up to just some time randomly loose your game... Please help, I love the game and want to play but can't make myself knowing that the game will kill itself at any point in time.
