Attacking other forum members is not the way to encourage people to help you with this. Their approach is direct, but accurate. The forums are a player help player area for the most part. Your DxDiag error section or the error reporting in an MSInfo might point to other clues as to why the clash is happening. All new tech support posts for issues like this one should include at least the DxDiag (requested in the pins by staff), but one hasn’t been posted yet.
However, if you are not interested in troubleshooting here and feel your concern is above us, please do go ahead and submit a ticket to Blizzard so you can work with their tech support staff. It does seem you will find the same info I’ve already provided (i.e. third-party software compatibility is outside their support), but maybe they’ll surprise me.
