Do you have any mods going?  Any modified core files?  Any previously created factions, sovereigns or units?  

I crashed everytime I tried to load a game, but knew it was probably because I was mucking around with mods.   In the end I don't think it was the mods, I think it was some custom factions/units I had in relation to the mods.     Cleaned out the custom factions and units (after turning off the damn steam synch - which kept replacing the deleted units/factions/sovs) and worked fine.    My docs\my games\LH - units and races I think.

Played 5+ hours (sheesh) with 1 crash - and crash was at 2gb memory in task manager.   Restarted game and no issues.

Good luck

Well that sucks.   Have you tried uninstalling, rebooting and re-installing?   Seems weird that you can get into the game - load everything up, play the game for a few minutes and THEN it crashes.   At that point everything should pretty much be loaded.    If it was only off loading save games (like my earlier issue) it stands to reason something in the loading process fails.   If its when doing X, it should be related to X.   Your symptoms seem really random though.  

Got any crazy security/virus protection that might be holding up a file as its trying to get loaded?  

Any issues playing other games?  Like maybe your hardware is getting flaky?  Overheating Ram or GPU?

Have you checked task manager when playing?  Possibly running out of memory?   I usually seem to be running at a gig to 1.5 gigs of ran for it.  It did crash once when I got up to 2 gigs but that could be unrelated.

Possibly running out of drive space?

Again, seems random that it would be affecting all those different actions.

I get occasional crashes too, almost always when the next turn is processing. I haven't found any solutions unfortunately.

I highly doubt it is faulty hardware.... I am experiencing the exact same issue, the game crashes every 10 minutes or so and it is very annoying. No mods, my drivers are up to date, nothing that I can tell that would make it continually CTD at random times.

Normal FE played fine, but LH is unplayable to me like this. 

I would be happy to! I can't link Dropbox here for some reason, so should I paste the log file or email it to you guys?

Thanks!

Hey, now it is working! My debug.err

Thanks gwn43, I will try that. Love FE and am really excited to play LH, just not when it keeps crashing  

yeah got the same Problem. Sometimes when i just finish some tasks => improve my cities, or look around my system goes "ups FE:LH doesnt react anymore" wanna close :/

I have the same issue: the game keeps crashing usually on the turn change. This only started happening relatively late in my game though, with lots of stuff happening between turns. Here is the crashdump file if it helps

Not sure if this has been mentioned here yet, but, for me the crashes have pretty much stopped once I switched Anti-Aliasing from 4x to OFF.

I used to get crashes pretty frequently once I got into the later part of the game, but, after reading somewhere on here about AA causing the problem I turned it off and it has worked marvelously.

Hopefully this is fixed at some point because it certainly does look nicer with 4x AA, but, for now I'll live without it so I can play the game. Because with it set to 4x the mid to late game just became a huge pain with frequent crashes regardless of what I did.
