There are some players who have already quit the game because they can't fix the problem they experience with the game. Some of them haven't experience the game in obt but after a server maintenance their pc will freeze and crash.
I'm not that good on technical problems with UWO but I hope this solution will help some of you there who had this kind of problem too. Thanks to this dude who posted what he did when his pc freeze while playing Uncharted Waters Online.
He pointed 2 things that has something to do with the game crash. Windows 7 and AVG.
It seems that GameGuard, the game’s anti-hack and cheat protection program, has some problems running with AVG. AVG, specially AVG 2011, sees it as a threat and blocks it from running and if GameGuard can’t run then the entire game won’t run either.
If you have this anti-virus installed in your computer it would be best to 1)uninstalled it, 2)change your AV, 3)disable your AVG and 4)add UWO to your AVG's exception list.
As for Windows 7, it seems that the game, Uncharted Waters Online, is not 100% compatible with the operating system. Running it on Windows 7 or even Windows Vista will cause instability which can lead to freezing or crashes.This is what he did for the Win7, run the game in Windows XP Service Pack 3 compatibility mode.
Though not all of the problem experience by players can solve this solution, it still depends on the machine you are using and the programs installed on it. I'll try to update this article for some error-solution i can find in the official forums of the game. So for now, enjoy your adventures!
