Ok...that's a godaddy issue, it's unlikely they will help you though.

Honestly, I ran zencarts on GoDaddy 6 years ago...haven't since...

Here is a blog post from mprough with issues she had: http://pro-webs.net/blog/2012/09/26/godaddy-epic-fail/

IMHO: I would recommend moving to a new host, not just because of this problem

One of the main reasons we started doing our own hosting was GoneDaddy. Admittedly, they are better now technically BUT, they also are good at the "oh, you wanted bandwidth with that?" and you will quickly find that "unlimited bandwidth" is certainly not.
If your host allows the installation of FrontPage or other vulnerable services (Wordpress is constantly being hacked) you are putting your Zen Cart at risk by staying with them.
