Cant install Theme. zipped file crashes

hi

Im having problems installing this theme. Have tried 5 times installing the zipped file i downloaded and each time after it reaches 100%, the next screen says ‘Are you sure you want to do this” Then a button that says “Try again” and it takes me back to the installation menu. Nothing is ever uploaded. I then created a rar file instead of a zipped file and after i uploaded that, the next error said this

Any ideas guys?

I have just installed the latest version of wordpress and have installed another theme to make sure it was me. Its just this theme.

the site is redfrogbookkeeping.com.au

thanks
