Windows 8/8.1/10 game start crash since new patch even ver 2

hi, my game start crashing like at least 4~5 times daily. no matter ver 1 or ver 2. by the time.
people told me that mute the sound will make it better. but unfortunately the game still crash.
please fix it. the DCs really killing me~

the attach file are the most of the time the error code im getting.

 

im using the latest one. sorry the pic i uploaded is old one. but the same error show. thats why i put it

 

hi kimmy. i just crash again inside HT after maintenance. this is the same error code shows. so far. i only crash inside boss run. ep: 3 HT and 2 PB in 5 days.

 

i just replace it in folder. but this time i just DC it like 2 mins after i log in.
and i keep getting crash the same error when i try to use sinpe on my marksman. i mean i can see the arrow going. but when almost hit the target. the gam just crash rightaway.

 

and i was fine with the game before the patch. when the server is like 39 days without maintenance. but after that starting crashing.

 

err. this happen again. when i use my NL to use ninja storm skill. immediately dc of each time i use that skill. ( this is happening when i remove the sound_dx8.dll )
i think i just put back the dll that comes with the patch one to play the game. hope ur team can fix it in the next maintenance. btw. as i mantion before. the game before the patch. i never DC in the boss run（ep:ht and PB). is it possibable to put that sound_dx8.dll file to fix it?

 

game start crashing again durning Boss run ( Toad this time ). the game just black screen and close game back to windows. it happens 2 times last weekend too. no more sound_DX error code. all 3 DCs are black screen and close it. i did open my game and AFK in FM or other town for more than 10 hours. nothing happen. but when i go boss. start to crash.
