Problem with google mail

Question

Google

This morning, having downloaded Google mail, I found that the settings were wrong and all letters go to one column clip2net.com/s/7gWv9C. I got into the settings, and there is still a module installed that divides the mail window into two windows. List and view. In the rest of the folders, by the way, everything works. Does anyone know what could be causing this and how to fix it?
