Reshy, I could be wrong but I don't think those issues sound like they could be caused by Exerelin. In fact the no error thing could mean it is an error beyond StarSector itself. It may be worth checking the windows event logs to see if there is something there.
It only happens with the mod installed, and I only have Lazy's Lib and Exerelin installed. I don't know how to view the windows event logs so if you can tell me I'll find what's in there when it crashes.
Before trying to debug anything, I want to verify that you have rebooted since this has started happening to you, and it is still occuring after the reboot. Sometimes people leave their computer on for extended periods (is totally not guilty of this.. :Shifty eyes:) and occasionally the computer just legitimately just needs a reboot.
Assuming you have rebooted and still have this problem, here is how to use the Event Viewer.
It would help if you told us which version of windows you are running, but for XP and 7 you should be able to find the event viewer in Start menu -> Control Panel -> Administrative Tools -> Event Viewer.
In Windows 7 you can also just type in 'Event Viewer' in the search box in the Start Menu.
Heaven Google help you if you are on Windows 8, because I can't.
I would check 'Application', 'Security', and 'System' logs under the 'Windows Logs' and the 'Hardware Events' under the 'Applications and Services Logs'
I would probably check it like this,
1. Take screenshots of the logs listed above, then close the Event Viewer.
2. Start the Game, When it crashes,
3. Close out anything the game has left (if it is frozen on white screen, then end process in the Task manager [push Ctrl + Shift + Esc, or Ctrl+ Alt + Del ->Task Manager])
4. Re-Open the Event Viewer and compare the entries to the screenshots and see if any new entries exist.
Good luck.
