Help! Live site went down, can't even access login anymore

Hi there,

I could really use some help. I was migrating a localhost wordpress site I had designed to a live site using All-in-One-WP Migration. Seemed easy enough.

After it said the content had migrated, it asked me to login. It said my username didnt exist and now when I try to access /wp-admin there is no login screen. Just ‘google chrome cannot find’

Please help! I have no idea what went wrong or what I should do now. Everything seems lost.
