Hi guys. When I try and download the client, it just closes without warning and no error messages appear. However I did manage to find an errors file which appears on the desktop when it closes. The jist of the error is as follows:

This application has encountered a critical error:

ERROR #1 (0x13370001) Fatal Exception
Program: C:\Users\kasper\Desktop\Diablo-III-Setup-enGB.exe
Exception: 0xC0000005 (ACCESS_VIOLATION) at 001B:100178D4

The instruction at "0x100178D4" referenced memory at "0x00000086".
The memory could not be read.

Crashed Thread: 0x00001394

Any help would be deeply appreciated, as I have paid for the game and it would be pretty annoying if it simply didn't work
