My client crashes at seemingly random times, I cannot do a specific action to reproduce it.
I tried running the repair after it happened three times, but it continued to happen afterwards.
I am attaching a screenshot of the error.
I can still play games and use the client effectively, and when it crashes I simply have to restart and log back in.
My OS is Windows 7 64bit. I'm not sure if it's related to the most recent patch, as I don't quite remember when it started.
