Integrating Shopsite into forum

[kiawah]

We purchased a license for shopsite and have been trying to install it in our forum.

The installer told us that the problem is:

The public_html/.htaccess file in this site that is created by (or
> for) your forum software contains extensive re-write rules that are
> affecting the rest of your site (any pages/directories that are not
> part of the forum software, in this case specifically the
> public_html/store directory and the public_html/cgi-bin/ directory).
>
> After installing ShopSite on this account, I was unable to login to
> the ShopSite.

In order to have the ShopSite stuff work at the same time on
> this account you will need to get with someone who knows/supports your
> forum software and find out what you can do to modify the rewrite
> rules in your custom public_html/.htaccess file to leave the store and
> cgi-bin directories alone.

Does anyone have experience with this shopping cart? Or can give me any advice?

Thanks!
