I got this game yesterday and played it all night without any problems, then I played a 2 hour game this morning and everything was working great. I went online, made an account and everything just fine, I couldn't host though. I exited the game and was going to restart when I noticed a McAfee message pertaining to Sins' internet ussage being blocked, which is probably why I couldn't host. I had already started the restart though and was unable to click "Grant access" before everything shut down. When I got back to the desktop, I found that I was completely unable to get into the game at all.
Double clicking on the shorcut brings up the launcher, but after hitting "Play the Game" it immediantly comes up with a "Microsoft Windows" box that says "Sins of a Solar Empire has stopped working. Checking for solution to your problem." A few seconds after that the box changes and says "A problem caused the program to stop working correctly, Windows will close the program and notify you if a solution is available." Then I have to hit a "Close Program" button to get out of the box.
I went to control panel and hit uninstall, then did a Repair. It went along, I assume re-installing the game, and at the end when I hit "Finish" came up with the exact same error. I'm a bit baffled as to why the game would be working so fine just an hour ago, and now it won't even get to the opening movie cutscene. Could that be it actually? I do remember checking an option box to disable to opening cutscene. Unfortunatly if I am unable to get into the game, I can not un-check this option and see if the problem goes away...
So what can I do? I have to go to work now, but latter I'm going to completely uninstall the whole thing(not like I have any saves or anything) and re-install it instead of just doing a repair. If there is an easier way though, I'd be glad to hear it.
