I was using the 5.2, after having enabled the 5.3 everything started to work again.
Thank you very much.
Upgrade from fullpackage is easy just copy all the files except the mainfile.php and install directory
run the upgrade from the upgrade directory and refresh your system module thats all
It seems that you are missing some files, and did you use the fullpackage or only the upgrade?
