After entering my authenticator code, this wordless dialogue box appears with a single button [Cancel] and refuses to proceed.
The problem lies with my account and not with the computer / network because attempts at logging into other accounts work as normal.
I would greatly appreciate it if you could look into this matter asap.
Edit : I did receive an email from Blizzard regarding suspicious activities from my account, and was directed to the password reset page. Upon entering my details, I was sent an email to the actual password change page where I could enter my new password. However, it seems that performing these actions as requested did not help resolve my problem.
