Please take a few moments to read over the pinned threads in this forum. You may be experiencing the Razer issue, or something similar, causing the game to hang instead of open.
Greetings all,
We’ve been working to improve some of the available troubleshooting resources for our games. We wanted to have a go-to resource for some of the most common technical issues you can experience in Blizzard games. Each of the following posts goes over a different type of technical problem and links to troubleshooting resources. If you continue to have problems after using our technical support articles, check the last expandable menu in this post for how to receive more help.
Befor…
After you review those, if you still need help, follow the instructions for providing a DxDiag here.
