Hass stopped

Configuration
1

After a reboot HASS won’t start. I get this error

sounds like the compiled version of the loader.py (loader.pyc) is corrupted. Are you using hassbian or hass.io?

I’am running hassbian.

I think you just need to recompile the pyc files by reload() or deleting the files. There’s probably a way to do it from cmd as well.
