J-BusinessDirectory - Cant' get Cron to work in business directory

I have Cpanel, crons are usually pretty straight forward, but this one isn't working. The cron error comes back as No input file specified. Is there a different way I should format the task? Perhaps the absolute path? What is that.

Hi,

There is no cron job in our product. You should create a cron job that access the notificaiton link. The cron is dependent base on system applications.

Hello-

Could you elaborate on the "notification link" you referred to? I was able to set up a cron job in my hosting, but I'm not receiving any emails letting me know it worked. 

I followed your instructions at this link http://yoursite/index.php/component/jbusinessdirectory?task=companies.checkBusinessAboutToExpire in the cron job command.

Is there already an executable file installed or do I need to write the script?

Any help would be appreciated.
