Add to cart shortcut breaks my price table

I am using CSS3 Responsive Web Pricing Tables Grids For WordPress, and I am trying to use this plugin to place an “add to cart” button on my table. When I place the shortcode into the appropriate area, it works only for the first table. If I use it on any consecutive table it breaks it completely. I wrote the makers of the price table and their response was:

It’s a bug in WP Simple Paypal Shopping cart plugin. It using “:” for saving its data and then it’s exploding data into array. I’m also using “:” sign for storing some table data and that plugin broke them. Line 475 (wp_shopping_cart.php):
$pieces = explode(‘:’,$m);

Is there any way to fix this?

Thank you.
