When I logged onto the app earlier it said there was an app update, but it was stuck at 0%, tried to update hots to play it and that wouldn’t work either. Look online for some solutions and they didn’t work then tried to reinstall but for some reason the installation is now also stuck at 0%. Found it odd cause just this afternoon I was playing hots on the same computer and some people were having router issues but it doesn’t fix with a VPN and another computer on the same network can still download.
Manage to solve the problem using this post Battlenet app not working anymore
Thanks for the useful reply Jayce
