Plutonium

I was just sharing my experiences with the equivalent error code stated above. I have read the error messages in the dump files. It was honestly just an oversight on my part not mentioning the actual error message.
The exception information is: The thread tried to read from or write to a virtual address for which it does not have the appropriate access.

I have the exact same problem. I have completely reinstalled Black Ops 2 and removed the Plutonium installation files. I find this issue seems to affect me on the majority of servers but not all of them. I can still play on a very small number of servers without any issues.
I have tried updating GPU drivers and the Plutonium software is completely excluded from my antivirus software. T6 used to run perfectly for me and then about 1-2 months ago this issue started happening out of the blue. I can use the other games with plutonium without issues. It is literally only Black Ops 2.
