LibreOffice 4.3.7.2 Developer identification needed?

Ever since I downloaded LibreOffice 4.3.7.2 on my Mac I now get this::

“LibreOffice.app” can’t be opened because the identity of the developer cannot be confirmed.

Your security preferences allow installation of only apps from the Mac App Store and identified developers.

Safari downloaded this file on 19May, 2015 from donate.libreoffice.org.

I am afraid to change my settings because of viruses. Also i am a Computer idiot.

Also this was the first time I donated. now i can’t use it.

Thanks in advance for your help.
