I have e-mailed the log to you from reynoldsandrew41
I got the error log! So, I think all of the first errors in your log are related to the problem I fixed. The last two errors basically say "An external component has thrown an exception" and reference the OpenALSoundController.
My working theory is that the game is trying to play too many sounds at once and crashing your specific collection of drivers or hardware. I may have made this worse in the Dec release because weapons typically fire more shots now. Based on your description and the error log, I'd guess that a bunch of ships try to fire a bunch of shots at once, crash the sound driver and the game.
This one will likely be a little harder to fix since I don't have a good way to test. But I have some ideas to get started on over the next few days. I'll let you know as soon as I have an update.
The fix for this is going to require a significant overhaul of the sound implementation. Unless it's causing regular crashes, I'm going to either fix this as part of the next major release or as a patch after the next release. I'd have to do a pretty big change in dev direction to get this fixed immediately and that would push out some really important stuff I'm working on for this release.
Thanks for your patience: I'll let you know when I have a fix underway!
