It's very unusual that you can't reach the character screen. I've heard of long loading times when in-game but not when loading ESO up. Is there perhaps a firewall blocking access in the background that you are unaware of?
well, i am going through a second repair for the night in hopes that the infinite loading screens i keep getting (three so far I have waited on) will eventually let me see my character select screen.
fix your isht zos!
