Hey there,

Limitations with Blizzard Support for Activision titles.
In regards to Activision, we only handle the distribution of the game client for Activision. We will assist with anything related to the desktop application and anything with the game client that involves purchasing, activating, downloading/installing and launching. Anything that occurs after you can press the play button is going to be addressed through the Activision support portal:

Given that this is happening on the steam client as well, indicates a larger system level issue that Activision Support will have more advice on.
