Game disconnects after returning to the city

  1. One day it works completely normally and the next it constantly slows down, the game freezes when I click on the pylon while wearing the Nemesis bracers and disconnects me when I try to return to the city. It only disconnects and not error 1016. I found hundreds in the d3debug.txt file:

What does this mean?

  1. If the game runs normally, there are only errors from FMOD and hence my request. Does anyone know where I can download fmodex.dll(x86) from HoTS? All the ones I downloaded from the net cause no sound in the game.

  2. The game can turn itself off and instead of appearing in active processes in the task manager, it changes the Background Processes location and the closed game hums on the desktop just like standing close to an open rift in a city. You can then run two copies of Diablo at once. How is that possible?
