Update Problems on Mac 360 v6

I'm having trouble updating my software. It seems to download so far then i get this message.Screen Shot 2014-08-11 at 20.32.14.png

 

I've been trying to see if i could download the software and reinstall from scratch again but i can't seem to see it on the website.

 

My Antivirus is not working because if the update errors, i'm getting this message

But when i try to update i get the original error message.

 

Any help would be appreciated.
