Q: Mavericks Installer Downloads, but will not run.

I am currently running Mountain Lion, I am trying to install Mavericks, but I am having strange issues.

 

The Installer downloads from the App Store, runs for a few minutes then returns the error: "This copy of the Install OS X Mavericks application can't be verified. It may have been corrupted or tampered with during downloading."

 

I checked my date and time prefences, and did everything in http://support.apple.com/kb/TS5307, still no luck.

 

 

Now I finally threw in the towel and decided to do a CLEAN INSTALL, I created a USB Recovery disk from another Mavericks Mac and booted from it on this Mac.  I deleted the hard drive, and proceeded to do the clean install, after the system completly downloads is simply takes me back to the main menu from the boot disk (where I can choose disk utility, time machiene, install Mac OS X....). 

 

The system will download the installer, but I cannot get the actual installer to run, even when booting from a Recovery Disk.

 

HELP!!!!!!!!!!

MacBook Pro with Retina display, OS X Mavericks (10.9)
