Hello and welcome!
Bad name index usually means that a file is corrupt. Did you get any errors when you used the installer that you downloaded? I will re-download and update the game to see if I get the same error, but you should try to update again.
Could you please post some more information about your system:
- Operating System (Windows 7 Pro, Windows 10 Home etc.)
- CPU model
- Graphics card model
- Amount of RAM (4GB, 8GB etc.)
Did you download the updater, or did you use the updater found inside the client?
Also, could you post a screenshot of what it looks like for you on the char creation screen?
