The file attached to this article is one that has had some success with GoDaddy hosting. This file assumes that you have installed Interspire Shopping Cart into a directory called shoppingcart. This file should replace your current .htaccess file in your store directory.
If you have installed it into another directory you will have to modify this file before uploading it.
For example if your shopping cart is installed in a directory called store, then the line
RewriteRule . /shoppingcart/index.php
Should be changed to
RewriteRule . /store/index.php
Or if your shopping cart installation is in the root of your site, change it to
RewriteRule . /index.php
