the plugin won't let me set up tax rates. The shopping cart was working perfectly until I installed a tax table. My whole site crashed and I had to delete the plugin and reinstall it.
Now, no matter what I do I can't add anything to the shopping cart, I'm not able to import tax tables. I've even disabled taxes and still when you hit to cart the site hangs up and nothing is added to the cart.
Where the heck do I look to fix this?
