I followed a youtube video, the link is https://www.youtube.com/watch?v=DEULs3ShTxo&list=PLnwIwnzAHNfi3mCaRDIXcQx8HtuWm1pqw&index=2
He said that while installing MIST, while downloading mist, he said that it will ask whether to download main network or testnet network. But it wasn't asked while i am downloading!! Also when installed mist, to select test network there are two networks one is ropsten and other is rinkeby. As per video I have selected Rinkeby network. When i am trying to create a new account -> the account is not creating eventhough i created(creation process, password and confirm password)!! Please tell me why it is happening!! The account is not created and the further process I am getting to continue as per the video.
