I just attempted to install the free version of the plugin through the WordPress plugin search before purchasing the Pro version.
I am getting the following error message: 

Parse error: syntax error, unexpected T_FUNCTION in /home8/. . . .wp-content/plugins/gs-portfolio/gs-portfolio-script.php on line 44

I looked at the file, but don’t see any errors that are evident to me.

Is there a way I can get the plugin files from another source.  I would like to verify that it will work on my site before purchasing. 

Thank you.
