when I select a server I get a funny noise, and an error box pops up.

DayZ_x64-application error

the instruction at 0xaf1fe116 referenced memory at 0x00000010 the memory could not be read

I was able to play .63 a few times, but yesterday every time I picked a server I dot this error. The 0xaf1fe116 # would change from time to time (possible based on server Im not sure), but otherwise same error. This happened maybe every time, maybe 15 times over several hours

I was/am able to play the game in offline mode just fine.

Today I am able to log into a server.
I have played for several years and have never seen this before.
