Re-install. You can try a to install over top of what you have (eg. without erasing the partition)...

My first idea was to reinstall over...but it doesn´t let me do it...the installer says i can´t because i´m installing a version older than the one i have on the disk! Is there any way to force this?

Update your USB installer.

You mean download Mavericks from Appstore again, and use Unibeast?

You will probably need to do a fresh install.
