Buffer overrun and other fun errors

While playing online Sins crashed to the desktop, and the error given was that a Buffer overrun had been detected and had corrupted the game's internal state, and the game could not continue.

Also, when I load the game the windows start button continuously flashes, and I have to click it, let Sins minimize, and re-maximize sins for it to go away.

I'm not sure what information is needed to best debug this?
