Downloaded Battle.net client for Windows
Every time I attempt to login it appears to load and then I get a message “Whoops! Something went wrong. Please wait a moment and try again”
I’ve tried loads of times now on different days and still no luck.
I’ve tried uninstalling and reinstalling. I tried deleting the Blizzard Entertainment folder (as found on another thread) and none of these work
This means I can’t download or play any games at the moment
Please help

Try changing your password. I was having the same issue today and that worked for me. It may be that Blizzard detected your password has been leaked somewhere.
That worked, thank you so much
Turns out I’ve not used Battlenet for a loooong time. I logged in on the site, went to change password and it asked me for other information and then said I needed to change my password
If the app had said that it would have saved a heap of trouble and me posting here!
Thanks for the reply though, massively appreciated 
In my case it turned out that I needed to provide my date of birth in the account settings. This is obvious when you log in through the web, but the battle.net app gives no indication of what to do … it just provides a this error message and “reload” button.
