That’s a bit weird! Was it working before you did something?
The first step would be to disable all plugins — since you can’t get at the Dashboard, the only way for you to do that would be to remove them from your wp-content/wp-plugins folder via FTP. Try moving them and see if that restores your Dashboard. If it does, add the plugins back one-by-one to find the one causing the issue.
These issues are very often caused by a plugin issue.
Good luck!
It was working before I changed Themes and updated to the newest WordPress update

I deleted everything dated today and yesterday since I had the problems and this is what I get now
Looks like your WordPress update didn’t complete or was corrupted. Your best bet would be to reinstall WordPress. You could try uploading /wp-includes from a copy of WordPress 3.7.
I’m not sure what you mean by you deleted everything dated today an yesterday, but from the error message, there is at least one file missing (/wpincludes/pomo/mo.php).
