I installed eCommerce, then was told wouldn't need it, so uninstalled it. THEN I was told it would be needed after all, so I attempted to RE-install it. During installation attempts, I continue to receive "500 Internal Server Error"s. In a fit of flaky desperation, I even removed the relevant tables from the database, but I'm getting nowhere. Any help would be appreciated.

Oh, and I found a thread that referred tohttp://www.concrete5.org/marketplace/addons/ecommerce/faq-how-to-un... for help, but I get a 404.

Thanks so much for your time!
