Jupiter Theme Installation

I have encountered several errors with my jupiter theme installation and have various php errors shown on my pages with demo content loaded. An example:

Warning: preg_replace(): Compilation failed: unknown option bit(s) set at offset 0 in /home/altonadmin/public_html/wp-includes/shortcodes.php on line 309

I now have a fresh install of WordPress with no theme installed. Can you advise me on how to get jupiter installed correctly. I assume some PHP will need to be edited.
