Ok so it is without a doubt the issue when i go to update the game here is the error

nnsstrm.exe
Page_Fault _in _ nonpaged_area

( huge error code which if needed i can type out )

collecting data for crash dump

might be a VM issue so im going to disable it like it says to try and see if this helps ..be very curious if anyone else has had this happen ?

Happened to me as well. I am using BitDefender and it still went bsod after disabling the program.

I'm also getting BSOD when trying to update. No Panda Antivirus.

okay I still get the bsod after I uninstalled my security program. I also completely uninstalled nvidia drivers (driver sweeper) and installed the latest drivers. So I am not so sure what is causing the blue screen.

I opened Battlenet application to play the game. The game started to load and got a message 'The application encountered an unexpected error.' Please use the Report ID below when communicating with Blizzard about this issue.

Not sure what is going on. Have tried more than 10 times to play this morning. Every time the game after I get the game is running it crashes and the unexpected error pops up.

anyone else having trouble playing the game after today's scheduled update?

still trying to get into play.....guess it wont happen today. I even attempted 4 times to send a tech ticket in. Each time I got the same response...An unknown error has occurred. Off to work hope that goes better than my 2 dozen attempts to play D3 today

ive disabled the only one i have to see if it woudl help ( Bit defender ) and still when i go to update ..exact same issue every time ...this is a first for me ..ive never had the problem before on updates ...what do you think is going on ..it seems other people are having the same problem

Guys I was able to get mine working. My bsod is mainly PAGE_FAULT_IN_NONPAGED_AREA, Bug Check Code: 0x00000050, Crash Address: ntoskrnl.exe+75c00. I did a lot of troubleshooting steps but the bsod went away after I ran chkdsk /f.

Ok ive tried everything ...ran the chkdsk/f uninstalled the ONLY program in the last while which was adobe reader ...still exact same bsod .. Now the only thing i can think of is this ..Omrakos said to disable PANDA ..i had issues with panda about 7 month ago where i couldn't uninstall it so i did a manual deletion of it from the registry ( it was massively corrupt for what ever reason and i wanted it gone fully ) so trying to put in a new anti virus it sid there was one already installed ..panda ..then i went to re install panda to see if i could remove it properly ..it says the same thing ...so i have bits of that stupid anti virus from months ago in my registry ..i just cant see it causing this tho ..ive done at least two updates from here since then ..i really need help ..i play everyday lol

and just to make triple sure its nothing else ..im doing a huge update on ESO right now ..no issues at all

ok will try again and let you know if any changes ( just searched ..there is no nnsstrm.exe in my computer lol )
